如何以编程方式更改Button的width.我可以更改height，但宽度不变.以下是我的代码段

How to change the width of a Button programmatically. I am able to change the height but the width does not change. Following is my code snippet

private void createButton(final String label)
{

    Button button = new Button(this);
    button.setText(label);


    button.setWidth(10);
    button.setHeight(100);

    button.setOnClickListener(new OnClickListener() 
    {

        @Override
        public void onClick(View v) 
        {


        }
    });
    mMenuContainer.addView(button, mMenuItemLayoutParamters);


}

但是Button的width占据了屏幕的width.

推荐答案

button.setLayoutParams(new LinearLayout.LayoutParams(10, 100));

应该为您工作.

您应该应用包含View的ViewGroup中的LayoutParams.也就是说，如果您的按钮位于RelativeLayout内，则应使用RelativeLayout.LayoutParams

you should apply LayoutParams of the ViewGroup that contains your View. That is, if your button is inside RelativeLayout, you should use RelativeLayout.LayoutParams
