Android仿淘寶商品詳情頁效果

更新時(shí)間：2018年10月26日 10:31:54 作者：小水缸

這篇文章主要為大家詳細(xì)介紹了Android仿淘寶商品詳情頁效果，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Android仿淘寶商品詳情頁的具體代碼，供大家參考，具體內(nèi)容如下

Demo地址：先上效果圖

效果就是上面圖片的效果接下來看看如何實(shí)現(xiàn)

首先我們來看下布局文件

 <LinearLayout
      android:id="@+id/header"
      android:layout_width="match_parent"
      android:layout_height="72dp"
      android:paddingTop="24dp"
      android:background="#00FFFFFF"
      android:orientation="horizontal">
 
      <ImageView
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_gravity="center"
        android:src="@drawable/back"
        />
      <View
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"/>
     <ImageView
       android:id="@+id/icon"
       android:layout_width="30dp"
       android:layout_height="30dp"
       android:src="@drawable/aa"
       android:layout_gravity="center"/>
      <View
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"/>
      <ImageView
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_gravity="center"
        />
 </LinearLayout>

這塊主要是設(shè)置剛進(jìn)入頁面時(shí)的透明頭部主要組成部分有返回鍵和頭部的方形小圖片還有分享按鈕以及你想附加的標(biāo)題功能默認(rèn)進(jìn)入是透明的只顯示返回按鈕

 <FrameLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content">
      <RadioGroup
        android:id="@+id/radioGroup"
        android:background="#00FFFFFF"
        android:layout_width="match_parent"
        android:orientation="horizontal"
        android:layout_height="48dp">
 
        <RadioButton
          android:layout_width="0dp"
          android:layout_height="match_parent"
          android:layout_weight="1"
          android:button="@null"
          android:textColor="#00000000"
          android:gravity="center"
          android:text="寶貝"/>
 
        <RadioButton
          android:layout_width="0dp"
          android:layout_height="match_parent"
          android:layout_weight="1"
          android:button="@null"
          android:textColor="#00000000"
          android:gravity="center"
          android:text="評價(jià)"/>
 
        <RadioButton
          android:layout_width="0dp"
          android:layout_height="match_parent"
          android:layout_weight="1"
          android:button="@null"
          android:textColor="#00000000"
          android:gravity="center"
          android:text="詳情"/>
 
        <RadioButton
          android:layout_width="0dp"
          android:layout_height="match_parent"
          android:layout_weight="1"
          android:gravity="center"
          android:button="@null"
          android:textColor="#00000000"
          android:text="推薦"/>
 
      </RadioGroup>
 
      <View
        android:id="@+id/layer"
        android:layout_width="match_parent"
        android:background="#00FFFFFF"
        android:layout_height="48dp"/>
</FrameLayout>

這部分主要是我們的標(biāo)簽選項(xiàng)卡我這邊采用的是RadioGroup+radioButton實(shí)現(xiàn)的類似于淘寶的商品、評價(jià)、詳情等標(biāo)簽

這樣我們的頁面布局頭部就完成了下面我們來看下具體組成內(nèi)容

<com.text.lg.ideascrollview.IdeaScrollView
    android:id="@+id/ideaScrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="vertical">
      <LinearLayout
        android:id="@+id/one"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        <com.text.lg.ideascrollview.IdeaViewPager
          android:id="@+id/viewPager"
          android:layout_width="match_parent"
          android:background="@drawable/aa"
          android:layout_height="wrap_content"/>
        <ImageView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:src="@drawable/one"/>
      </LinearLayout>
 
      <LinearLayout
        android:id="@+id/two"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        <ImageView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:src="@drawable/two"/>
 
        <ImageView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:src="@drawable/three"/>
      </LinearLayout>
 
      <ImageView
        android:id="@+id/three"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/four"/>
      <LinearLayout
        android:id="@+id/four"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        <ImageView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:src="@drawable/five"/>
 
        <ImageView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:src="@drawable/six"/>
        <ImageView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:src="@drawable/six"/>
        <ImageView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:src="@drawable/six"/>
      </LinearLayout>
 
    </LinearLayout>
</com.text.lg.ideascrollview.IdeaScrollView>

這部分就是我們的具體頁面內(nèi)容可以看到我們的詳情頁面數(shù)據(jù)使用自定義的一個(gè)Scrollview來包裹的其中分為4塊我們布局里面寫的很清楚分別對應(yīng)著詳情頁中的四個(gè)模塊當(dāng)然我這里面只是用圖片來代替內(nèi)容了具體內(nèi)容可自己填充

下面來看下我們具體實(shí)現(xiàn)代碼

StatusBarCompat.translucentStatusBar(this);

我這邊是采用的第三方的沉浸式透明狀態(tài)欄你們可以自行替換

dependencies {
    compile ('com.github.niorgai:StatusBarCompat:2.1.4', {
      exclude group: 'com.android.support'
    })
  }

這個(gè)是我沉浸式狀態(tài)欄的依賴感興趣的可以了解一下

 Rect rectangle= new Rect();
    getWindow().getDecorView().getWindowVisibleDisplayFrame(rectangle);
    ideaScrollView.setViewPager(viewPager,getMeasureHeight(headerParent)-rectangle.top);
    icon.setImageAlpha(0);
    radioGroup.setAlpha(0);
    radioGroup.check(radioGroup.getChildAt(0).getId());

上面是獲取狀態(tài)欄的高度并且使用自定義scrollview綁定banner圖片并獲取圖片高度

以及初始化我們頭部部分控件的透明度和默認(rèn)選擇第一個(gè)標(biāo)簽

View one = findViewById(R.id.one);
View two = findViewById(R.id.two);
View four = findViewById(R.id.four);
View three = findViewById(R.id.three);
ArrayList<Integer> araryDistance = new ArrayList<>();
 
araryDistance.add(0);
araryDistance.add(getMeasureHeight(one)-getMeasureHeight(headerParent));
araryDistance.add(getMeasureHeight(one)+getMeasureHeight(two)-getMeasureHeight(headerParent));  
 
araryDistance.add(getMeasureHeight(one)+getMeasureHeight(two)+getMeasureHeight(three)-getMeasureHeight(headerParent));
 
ideaScrollView.setArrayDistance(araryDistance);

這塊是我們獲取到我們的四個(gè)模塊的高度并把高度存到集合中傳入到我們自定義的scrollview中

private void scrollToPosition(int position){
    scrollTo(0,arrayDistance.get(position));
  }

scrollview通過傳過來的高度進(jìn)行定位滑動意思就是點(diǎn)擊我們的標(biāo)題選項(xiàng)滑動到相應(yīng)的位置

 public int getMeasureHeight(View view){
    int width = View.MeasureSpec.makeMeasureSpec(0,
        View.MeasureSpec.UNSPECIFIED);
    int height = View.MeasureSpec.makeMeasureSpec(0,
        View.MeasureSpec.UNSPECIFIED);
    view.measure(width, height);
    return view.getMeasuredHeight();
  }

這個(gè)是獲取控件高度的方法

ideaScrollView.setOnScrollChangedColorListener(new IdeaScrollView.OnScrollChangedColorListener() {
      @Override
      public void onChanged(float percentage) {
 
        int color = getAlphaColor(percentage>0.9f?1.0f:percentage);
        header.setBackgroundDrawable(new ColorDrawable(color));
        radioGroup.setBackgroundDrawable(new ColorDrawable(color));
        icon.setImageAlpha((int) ((percentage>0.9f?1.0f:percentage)*255));
        radioGroup.setAlpha((percentage>0.9f?1.0f:percentage)*255);
 
        setRadioButtonTextColor(percentage);
 
      }
 
      @Override
      public void onChangedFirstColor(float percentage) {
 
      }
 
      @Override
      public void onChangedSecondColor(float percentage) {
 
      }
    });

這個(gè)監(jiān)聽方法是監(jiān)測我們滑動的距離來改變我們標(biāo)題的顏色從透明慢慢滑動進(jìn)行顏色漸變以及設(shè)置我們頭部控件的顏色和展示我們的標(biāo)題選項(xiàng)卡

public int getAlphaColor(float f){
    return Color.argb((int) (f*255),0x09,0xc1,0xf4);
  }
 
  public int getLayerAlphaColor(float f){
    return Color.argb((int) (f*255),0x09,0xc1,0xf4);
  }
 
  public int getRadioCheckedAlphaColor(float f){
    return Color.argb((int) (f*255),0x44,0x44,0x44);
  }
 
  public int getRadioAlphaColor(float f){
    return Color.argb((int) (f*255),0xFF,0xFF,0xFF);
  }

可以根據(jù)這塊來改變我們頭部以及標(biāo)題的顏色根據(jù)傳入的值來進(jìn)行顏色漸變

 ideaScrollView.setOnSelectedIndicateChangedListener(new IdeaScrollView.OnSelectedIndicateChangedListener() {
      @Override
      public void onSelectedChanged(int position) {
        isNeedScrollTo = false;
        radioGroup.check(radioGroup.getChildAt(position).getId());
        isNeedScrollTo = true;
      }
    });
 
    radioGroup.setOnCheckedChangeListener(radioGroupListener);
 
 private RadioGroup.OnCheckedChangeListener radioGroupListener =new RadioGroup.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {
      for(int i=0;i<radioGroup.getChildCount();i++){
        RadioButton radioButton = (RadioButton) radioGroup.getChildAt(i);
        radioButton.setTextColor(radioButton.isChecked()?getRadioCheckedAlphaColor(currentPercentage):getRadioAlphaColor(currentPercentage));
        if(radioButton.isChecked()&&isNeedScrollTo){
          ideaScrollView.setPosition(i);
        }
      }
    }
  };

根據(jù)這兩個(gè)監(jiān)聽方法來改變我們標(biāo)題的選中tab 滑動到不同的位置選中對應(yīng)的Tab并改變顏色具體實(shí)現(xiàn)方法看自定義Scrollview

根據(jù)限定距離（Banner）計(jì)算百分比偏移量，實(shí)現(xiàn)顏色漸變、透明度漸變（淘寶商品詳情頁有二次顏色漸變）

@Override
  protected void onScrollChanged(int l, int t, int oldl, int oldt) {
    super.onScrollChanged(l, t, oldl, oldt);
    if (viewPager != null && t != oldt) {
      viewPager.setTranslationY(t/2);
    }
 
    if(viewPager!=null&&t<=point.x-headerHeight&&getOnScrollChangedColorListener()!=null){
 
      getOnScrollChangedColorListener().onChanged(Math.abs(t)/Float.valueOf(point.x-headerHeight));
      if(t<=(point.x-headerHeight)/2){
        getOnScrollChangedColorListener().onChangedFirstColor(t/(point.x-headerHeight)/2);
      }else{
        getOnScrollChangedColorListener().onChangedSecondColor((t-(point.x-headerHeight)/2)/(point.x-headerHeight)/2);
      }
 
    }
 
    int currentPosition = getCurrentPosition(t,arrayDistance);
    if(currentPosition!=position&&getOnSelectedIndicateChangedListener()!=null){
      getOnSelectedIndicateChangedListener().onSelectedChanged(currentPosition);
    }
    this.position = currentPosition;
  }
 
  private int getCurrentPosition(int t, ArrayList<Integer> arrayDistance) {
 
    int index = 0;
    for (int i=0;i<arrayDistance.size();i++){
      if(i==arrayDistance.size()-1){
        index = i;
      }else {
        if(t>=arrayDistance.get(i)&&t<arrayDistance.get(i+1)){
          index = i;
          break;
        }
      }
    }
    return index;
  }

下面是自定義Scrollview的全部代碼

  point = new Point();
  windowManager.getDefaultDisplay().getSize(point);
 }
 
 @Override

  super.onScrollChanged(l, t, oldl, oldt);
  if (viewPager != null && t != oldt) {
   viewPager.setTranslationY(t/2);
  }
 
  if(viewPager!=null&&t<=point.x-headerHeight&&getOnScrollChangedColorListener()!=null){
 
   getOnScrollChangedColorListener().onChanged(Math.abs(t)/Float.valueOf(point.x-headerHeight));

   }else{

   }
 
  }
 
  int currentPosition = getCurrentPosition(t,arrayDistance);
  if(currentPosition!=position&&getOnSelectedIndicateChangedListener()!=null){
   getOnSelectedIndicateChangedListener().onSelectedChanged(currentPosition);
  }
  this.position = currentPosition;
 }
 
 private int getCurrentPosition(int t, ArrayList<Integer> arrayDistance) {
 
  int index = 0;
  for (int i=0;i<arrayDistance.size();i++){
   if(i==arrayDistance.size()-1){
    index = i;
   }else {
    if(t>=arrayDistance.get(i)&&t<arrayDistance.get(i+1)){
     index = i;
     break;
    }
   }
  }
  return index;
 }
 
 private void scrollToPosition() {
  scrollToPosition(position);
 }
 
 private void scrollToPosition(int position){
  scrollTo(0,arrayDistance.get(position));
 }
 
 public void setViewPager(IdeaViewPager viewPager,int headerHeight){
  this.viewPager = viewPager;
  this.headerHeight = headerHeight;
 }
 
 public interface OnScrollChangedColorListener{
 
  void onChanged(float percentage);
 
  void onChangedFirstColor(float percentage);
 
  void onChangedSecondColor(float percentage);
 
 }
 
 public interface OnSelectedIndicateChangedListener{
 
  void onSelectedChanged(int position);
 }
 
 private OnSelectedIndicateChangedListener onSelectedIndicateChangedListener;
 
 private OnScrollChangedColorListener onScrollChangedColorListener;
 
 public OnScrollChangedColorListener getOnScrollChangedColorListener() {
  return onScrollChangedColorListener;
 }
 
 public void setOnScrollChangedColorListener(OnScrollChangedColorListener onScrollChangedColorListener) {
  this.onScrollChangedColorListener = onScrollChangedColorListener;
 }
 
 public IdeaViewPager getViewPager() {
  return viewPager;
 }
 
 public int getPosition() {
  return position;
 }
 
 public void setPosition(int position) {
  this.position = position;
  scrollToPosition();
 }
 
 public ArrayList<Integer> getArrayDistance() {
  return arrayDistance;
 }
 
 public void setArrayDistance(ArrayList<Integer> arrayDistance) {
  this.arrayDistance = arrayDistance;
 }

  return onSelectedIndicateChangedListener;
 }
 
 public void setOnSelectedIndicateChangedListener(OnSelectedIndicateChangedListener onSelectedIndicateChangedListener) {
  this.onSelectedIndicateChangedListener = onSelectedIndicateChangedListener;
 }
}

以上代碼就實(shí)現(xiàn)了文中效果圖樣式。
