将位置视图放在不同的位置

Question

我想将图标（图像浏览）放在更大的图像视图上。这样的事情：

ArrayList<Icon> icons = new ArrayList<Icons>; 
for(Icon icon : icons){ 
    ImageView iv = new ImageView(this); 
    iv.setLayoutParams(new LinearLayout.LayoutParams(
           LinearLayout.LayoutParams.WRAP_CONTENT, 
           LinearLayout.LayoutParams.WRAP_CONTENT)); 
    iv.setImageBitmap(icon.getBitMap()); 
    iv.setPosition(icon.getX(),icon.getY()); //Thats the line I need to know 
    myLayout.addView(iv); 
} 

但问题是我找不到一种方法，使其效率和知道哪个imageview被点击。

Answer 1

通过视图的标签，我发现我的定位问题的解决方案，你可以这样做：

ImageView imageView = (ImageView)findViewById(R.id.imageView); 
imageView.setX(xPosition); 
imageView.setY(YPosition); 

问题与，哪个图片被点击，回答@霍布乔很好，这个样本！

ArrayList<Icon> icons = new ArrayList<Icons>; 
for(int i = 0; i < icons.size(); i++) { 
    Icon icon = icons.get(i); 
    ImageView iv = new ImageView(this); 
    iv.setTag(i); 
    iv.setLayoutParams(new LinearLayout.LayoutParams(
           LinearLayout.LayoutParams.WRAP_CONTENT, 
           LinearLayout.LayoutParams.WRAP_CONTENT)); 
    iv.setImageBitmap(icon.getBitMap()); 
    iv.setOnClickListener(new View.OnClickListener({ 
     @Override 
     public void onClick(View view) { 
      iconClicked(view); 
     } 
    }); 
    myLayout.addView(iv); 
} 


public void iconClicked(View view) { 
    switch((Integer) view.getTag()) 
     case 0: 
      //... 
      break; 
     case 1: 
      //... 
      break; 
     default: 
      break; 
    } 
}

为了弄清楚单击的视图，应用标签，然后检查与onClick()

ArrayList<Icon> icons = new ArrayList<Icons>; 
for(int i = 0; i < icons.size(); i++) { 
    Icon icon = icons.get(i); 
    ImageView iv = new ImageView(this); 
    iv.setTag(i); 
    iv.setLayoutParams(new LinearLayout.LayoutParams(
           LinearLayout.LayoutParams.WRAP_CONTENT, 
           LinearLayout.LayoutParams.WRAP_CONTENT)); 
    iv.setImageBitmap(icon.getBitMap()); 
    iv.setOnClickListener(new View.OnClickListener({ 
     @Override 
     public void onClick(View view) { 
      iconClicked(view); 
     } 
    }); 
    myLayout.addView(iv); 
} 


public void iconClicked(View view) { 
    switch((Integer) view.getTag()) 
     case 0: 
      //... 
      break; 
     case 1: 
      //... 
      break; 
     default: 
      break; 
    } 
}
