动态图像按钮不调整大小

Question

这里是我的LinearLayout中生成的按钮的ArrayList，事情是，我已经在24x24中指出了大小，但是当我模拟它时，它根本没有调整大小。请帮我，我将不胜感激：d

public void generate_btnRemoveContact() 
    { 
     LinearLayout.LayoutParams lytContactParams=new LinearLayout.LayoutParams(24,24); 
     lytContactParams.weight=.5f; 
     btnRemoveContact.add(new ImageButton(getApplicationContext())); 
     btnRemoveContact.get(cntContact); 
     btnRemoveContact.get(cntContact).setScaleType(ImageView.ScaleType.FIT_CENTER); 
     btnRemoveContact.get(cntContact).setImageResource(R.drawable.ic_remove_circle_outline_red_24dp); 
     btnRemoveContact.get(cntContact).setBackgroundColor(Color.TRANSPARENT); 
     btnRemoveContact.get(cntContact).setTag(cntContact); 
     btnRemoveContact.get(cntContact).setId(cntContact); 

     btnRemoveContact.get(cntContact).setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       for (int rmvCnt = v.getId(); rmvCnt < cntContact; rmvCnt++) { 
        Toast.makeText(getApplicationContext(), "you selected " + rmvCnt, Toast.LENGTH_LONG).show(); 
       } 
      } 
     });' 



     lytContact.addView(btnRemoveContact.get(cntContact)); 

     cntContact++; 

    }

从您发布的代码，你需要设置上的ImageButton的的LayoutParams：

btnRemoveContact.get(cntContact).setLayoutParams(lytContactParams);
