如何查看Android手机是横屏还是竖屏?
当前回答
下面是hackbod和Martijn推荐的如何获得屏幕方向的代码片段演示:
改变时触发
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
int nCurrentOrientation = _getScreenOrientation();
_doSomeThingWhenChangeOrientation(nCurrentOrientation);
}
将当前方向设置为hackbod
private int _getScreenOrientation(){
return getResources().getConfiguration().orientation;
}
还有其他方法可以获得当前屏幕方向,参照Martijn方案:
private int _getScreenOrientation(){
Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
return display.getOrientation();
}
★注意: 我试过这两种实现,但在RealDevice (NexusOne SDK 2.3) Orientation上,它返回了错误的方向。
★所以我推荐使用解决方案来获得屏幕定位,有更多的优势:清楚,简单,工作就像一个魅力。
★仔细检查方向回归,以确保符合我们的预期(可能有限制取决于物理设备规格)
希望能有所帮助,

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;
}
用这种方法,
int orientation = getResources().getConfiguration().orientation;
String Orintaion = "";
switch (orientation)
{
case Configuration.ORIENTATION_UNDEFINED: Orintaion = "Undefined"; break;
case Configuration.ORIENTATION_LANDSCAPE: Orintaion = "Landscrape"; break;
case Configuration.ORIENTATION_PORTRAIT: Orintaion = "Portrait"; break;
default: Orintaion = "Square";break;
}
在字符串中,你有方向
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
}
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;
}
Android SDK可以很好地告诉你:
getResources().getConfiguration().orientation
