调整布局方向在Java设备的方向不是XML [英] Adjusting layout Orientation with the device orientation in JAVA not XML

问题描述

我想知道我怎么能根据JAVA设备的方向改变我的LinearLayout方向，我发现如何通过XML的方式与布局和布局土地做，但我没有找到如何在java做方式。

I wanted to know how i could change my LinearLayout orientation according to the device Orientation in JAVA, i found how to do it by the XML way with layout and layout-land but i didn't find how doing it by the java way.

非常感谢你。

推荐答案

请参见此内容它描述了如何检测方向改变然后更改在Java的方向

See this it describes how to Detect Orientation Changed then change orientation in java

在的onCreate（）

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

     setContentView(R.layout.activity_main);
     linearlayout=........;

     if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
     // landscape
     linearlayout.setOrientation(LinearLayout.HORIZONTAL); 
     }
     else {
    // portrait  
    linearlayout.setOrientation(LinearLayout.VERTICAL); 
     }
     ....
    }

和 onConfigurationChanged（）

public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
       // landscape
       linearlayout.setOrientation(LinearLayout.HORIZONTAL);
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
     //  portrait
        linearlayout.setOrientation(LinearLayout.VERTICAL);
    }
  }
