imageButton在布局的底部绘制

Question

我在代码中创建了ImageButton，

    // Create Button 
    ImageButton imageButton = new ImageButton(mContext);
    imageButton.setBackgroundResource(R.drawable.button);

    imageButton.setOnClickListener(this);
    LayoutParams myParams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

    addContentView(imageButton, myParams);

我如何在布局的底部绘制它？

Answer 1

尝试：

LinearLayout.LayoutParams lp= (LinearLayout.LayoutParams)myButton.getLayoutParams(); 
lp.layout_gravity=Gravity.BOTTOM; 
myButton.setLayoutParams(lp);
