如何查看Android手机是横屏还是竖屏?
当前回答
我认为使用getRotationv()没有帮助,因为 http://developer.android.com/reference/android/view/Display.html#getRotation%28%29 getRotation()返回屏幕从其“自然”方向的旋转。
所以除非你知道“自然”方向,旋转是没有意义的。
我找到了一个更简单的方法
Display display = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
if(width>height)
// its landscape
请告诉我这个人有什么问题吗?

有很多方法可以做到这一点,这段代码适合我
if (this.getWindow().getWindowManager().getDefaultDisplay()
.getOrientation() == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) {
// portrait mode
} else if (this.getWindow().getWindowManager().getDefaultDisplay()
.getOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
// landscape
}
在运行时检查屏幕方向。
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
}
}
我认为这个解决方案很容易检验的是景观
public static boolean isLandscape(Context context) {
final int rotation = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getRotation();
if (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) {
return false;
}
return rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270;
}
这样就覆盖了所有的手机,如oneplus3
public static boolean isScreenOrientationPortrait(Context context) {
return context.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT;
}
正确代码如下:
public static int getRotation(Context context) {
final int rotation = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getOrientation();
if (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) {
return Configuration.ORIENTATION_PORTRAIT;
}
if (rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270) {
return Configuration.ORIENTATION_LANDSCAPE;
}
return -1;
}
你可以使用这个(基于这里):
public static boolean isPortrait(Activity activity) {
final int currentOrientation = getCurrentOrientation(activity);
return currentOrientation == ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT || currentOrientation == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
}
public static int getCurrentOrientation(Activity activity) {
//code based on https://www.captechconsulting.com/blog/eric-miles/programmatically-locking-android-screen-orientation
final Display display = activity.getWindowManager().getDefaultDisplay();
final int rotation = display.getRotation();
final Point size = new Point();
display.getSize(size);
int result;
if (rotation == Surface.ROTATION_0
|| rotation == Surface.ROTATION_180) {
// if rotation is 0 or 180 and width is greater than height, we have
// a tablet
if (size.x > size.y) {
if (rotation == Surface.ROTATION_0) {
result = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
} else {
result = ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE;
}
} else {
// we have a phone
if (rotation == Surface.ROTATION_0) {
result = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
} else {
result = ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
}
}
} else {
// if rotation is 90 or 270 and width is greater than height, we
// have a phone
if (size.x > size.y) {
if (rotation == Surface.ROTATION_90) {
result = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
} else {
result = ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE;
}
} else {
// we have a tablet
if (rotation == Surface.ROTATION_90) {
result = ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
} else {
result = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
}
}
}
return result;
}
