Question

我有两个按钮，想要在同一页面上点击按钮更改布局内容按钮位于顶部。

我想通过单击按钮更改此xml中的特定区域内容。

就像在两页之间切换一样。

提前致谢

它在logcat中显示此异常

你的布局中需要一个容器 - 比如说LinearLayout。然后你需要在你的活动中引用它。

LinearLayout container = (LinearLayout) findViewById( R.id.myContainer );

然后您需要为按钮创建onClickListener：

private class OnButtonClicked implements OnClickListener {
   private void onClick( View v ) {
      //First we remove what is in the container
      container.removeAllViews();

      //Then we add the new content
      container.addView( newContent );
   }
}

newContent可以是使用LayoutInflater充气的任何视图。

请务必添加OnClickListener：

myButton.setOnClickListener( new OnButtonClicked() );

如何夸大布局？
