Android横屏竖屏设置

博客分类：

• Android

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);//设置成全屏模式

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE););//强制为横屏

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);//竖屏

我做的东西里面还用到了去掉标题栏。
我也贴出来
requestWindowFeature(Window.FEATURE_NO_TITLE);

 

 

垂直居中： 

android:layout_centerVertical="true"

 

水平居中：

android:layout_centerHorizontal="true"

 

1.hideStatusbarAndTitlebar()隐藏statusbar和titlebar.

private void hideStatusbarAndTitlebar() {
    final Window win = getWindow();
    // No Statusbar
    win.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    // No Titlebar
    requestWindowFeature(Window.FEATURE_NO_TITLE);
}

2.设置屏幕显示模式ScreenOrientation.

在activity里设置android:screenOrientation的值。
android:screenOrientation的属性有以下值：
unspecified(默 认值，由系统判断状态自动切换),The default value. The system chooses the orientation. The policy it uses, and therefore the choices made in specific contexts, may differ from device to device.
landscape,横屏
portrait,竖屏
user(用户当前设置的orientation值),The user's current preferred orientation.
behind(下一个要显示的Activity的orientation值),The same orientation as the activity that's immediately beneath it in the activity stack.
sensor(传 感器的方向),The orientation determined by a physical orientation sensor. The orientation of the display depends on how the user is holding the device; it changes when the user rotates the device.
nosensor(不 使用传感器，这个效果差不多等于unspecified).An orientation determined without reference to a physical orientation sensor. The sensor is ignored, so the display will not rotate based on how the user moves the device. Except for this distinction, the system chooses the orientation using the same policy as for the "unspecified" setting.

3.水平/垂直居中的方法.

设置parent的android:gravity为"center"。

4.获得当前屏幕宽高的方法.

Display display = getWindowManager().getDefaultDisplay();
Config.screenWidth = display.getWidth();
Config.screenHeight = display.getHeight();
