我想以编程方式进行相对布局并设置android:layout_widht = 60 android:layout_height = 60.当我以编程方式执行时,它是否填满所有屏幕?我怎样才能做到这一点?

我的代码:`

      RelativeLayout relativeLayout=new RelativeLayout(getContext());
        RelativeLayout.LayoutParams rel_btn = new RelativeLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        rel_btn.height = 60;
        rel_btn.width = 60;
        relativeLayout.setLayoutParams(rel_btn);
 this.setBackgroundResource(com.example.R.drawable.line);`

屏幕: enter image description here

答案 0 :(得分:7)

btn.getLayoutParams().width = width;
btn.getLayoutParams().height = height;

实际上,只需使用

RelativeLayout.LayoutParams rel_btn = new RelativeLayout.LayoutParams(
            60, 60);

没关系。问题可能是背景图片拉伸按钮
