android-顯示相對布局和imageview

顯示相對布局和imageview

動態添加RelativeLayout和ImageView，但是在模擬器中運行沒顯示

代碼

RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(     
RelativeLayout.LayoutParams.WRAP_CONTENT, 
RelativeLayout.LayoutParams.WRAP_CONTENT);
ImageView iv = new ImageView(this);         
iv.setImageResource(R.drawable.freshface_mmm);
relativeLayout.addView(iv,lp);

最佳回答：

你還要把你的relativeLayout添加到activity裡.
addContentView(view, params)
