爲onClick監聽器設置動態添加的自定義視圖

Question

我需要滾動自定義視圖。爲了達到這個目的，我在XML佈局中做了一個scrollview，並添加了Relativelayout作爲其唯一的孩子。然後在運行時，我在RelativeLayout中添加自定義視圖。
CustomView類代碼如下：

public class CustomView extends View { 

int bgColor ; 
Point x ; 
Point y ; 
Point z ; 
int itemHeight; 
String tag; 


public CustomView(Context context) { 
    super(context); 
} 

public void setParameters (int bgColor , Point a , Point b , Point c, int itemHeight , String text) 
{ 
    this.bgColor = bgColor; 
    this.x = a; 
    this.y = b; 
    this.z = c; 
    this.itemHeight = itemHeight; 
    this.tag = text; 
} 

public CustomView(Context context, AttributeSet attrs) { 
    super(context, attrs); 
} 

@Override 
protected void onDraw(Canvas canvas) { 
    super.onDraw(canvas); 
    Paint paint = new Paint(); 
    paint.setStrokeWidth(4); 
    paint.setColor(bgColor); 
    paint.setStyle(Paint.Style.FILL_AND_STROKE); 
    paint.setAntiAlias(true); 
    Point a = new Point(x.x, x.y); 
    Point b = new Point(y.x, y.y); 
    Point c = new Point(z.x, z.y); 
    Path path = new Path(); 
    path.setFillType(Path.FillType.EVEN_ODD); 
    path.moveTo(x.x,x.y); 
    path.lineTo(b.x, b.y); 
    path.lineTo(c.x, c.y); 
    path.lineTo(a.x, a.y); 
    path.close(); 

    canvas.drawPath(path, paint); 

    /* paint.setTextSize(60); 
    canvas.drawText("h o m e",60,76,paint);*/ 


} 

@Override 
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
    super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
     setMeasuredDimension(widthMeasureSpec , resolveSize(itemHeight , heightMeasureSpec)); 
} 

public String getCustomTag(){ 
    return this.tag; 
} 



public String getColor(){ 
    return bgColor +" "; 
} 

}

這是在RelativeLayout的在運行時添加自定義視圖的方法：

private void drawViewsTest(int numItems,int screenWidth,int itemHeight,Context ctx) 
    { 
    Point firstPoint = new Point(0,0) ; 
    Point secondPoint = new Point (0,itemHeight); 
    Point thirdPoint = new Point (screenWidth,itemHeight/2); 

    view = new CustomView[numItems]; 
    for(int i = 0; i < numItems; i++){ 
     view[i] = new CustomView(ctx); 
     if(i%2 == 0){ 
      view[i].setParameters(Color.BLACK, firstPoint, secondPoint, thirdPoint, secondPoint.y, "men" + " "); 
      view[i].startAnimation(an); 
     }else{ 
      view[i].setParameters(Color.RED, firstPoint, secondPoint, thirdPoint, secondPoint.y, "women" + " "); 
      view[i].startAnimation(anTwo); 
     } 
     view[i].setId(i + 1); 
     view[i].setOnClickListener(this); 
     firstPoint = thirdPoint; 
     thirdPoint = secondPoint; 
     secondPoint = new Point(firstPoint.x , firstPoint.y+itemHeight); 
     rl.addView(view[i]); 
    } 
    setContentView(v); 

}

我的問題是內部我爲每個視圖註冊onClickListener，爲每個視圖註冊setId。但在clicklistener裏面，無論我點擊哪個視圖，都會返回最後添加視圖的ID。 任何建議，將不勝感激。！

這是監聽器代碼

@Override 
public void onClick(View view) { 
    Log.e("Tag is " , view.getId() +""); 
} 

Answer 1

view[i].setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 


     } 
    }); 

Answer 2

更改您的for循環了這一點。

for(int i = 0; i < numItems; i++){ 
      view[i] = new CustomView(ctx); 
      if(i%2 == 0){ 
       view[i].setParameters(Color.BLACK, firstPoint, secondPoint, thirdPoint, secondPoint.y, "men" + " "); 
       view[i].startAnimation(an); 
      }else{ 
       view[i].setParameters(Color.RED, firstPoint, secondPoint, thirdPoint, secondPoint.y, "women" + " "); 
       view[i].startAnimation(anTwo); 
      } 
      view[i].setTag(i + 1); 
      view[i].setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
     if(v.getTag()!=null) 
     { 
      int id=Integer.parseInt(v.getTag().toString()) 
      { 

      } 
     } 

     } 
    }); 
      firstPoint = thirdPoint; 
      thirdPoint = secondPoint; 
      secondPoint = new Point(firstPoint.x , firstPoint.y+itemHeight); 
      rl.addView(view[i]); 
     } 

Answer 3

Check whether its works for you 
private void drawViewsTest(int numItems,int screenWidth,int itemHeight,Context ctx) 
     { 
     Point firstPoint = new Point(0,0) ; 
     Point secondPoint = new Point (0,itemHeight); 
     Point thirdPoint = new Point (screenWidth,itemHeight/2); 


     for(int i = 0; i < numItems; i++){ 
      CustomView view = new CustomView(ctx); 
      if(i%2 == 0){ 
       view .setParameters(Color.BLACK, firstPoint, secondPoint, thirdPoint, secondPoint.y, "men" + " "); 
       view .startAnimation(an); 
      }else{ 
       view .setParameters(Color.RED, firstPoint, secondPoint, thirdPoint, secondPoint.y, "women" + " "); 
       view .startAnimation(anTwo); 
      } 
      view .setTag("viewID"+i); 
      view .setOnClickListener(this); 
      firstPoint = thirdPoint; 
      thirdPoint = secondPoint; 
      secondPoint = new Point(firstPoint.x , firstPoint.y+itemHeight); 
      rl.addView(view); 
     } 
     setContentView(v);
