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));
