Freeze screen orientation
android, android-screen, screen-orientation
Solution
So, here is my solution.
private int getCurentOrientation() {
Display d = ((WindowManager) getSystemService(WINDOW_SERVICE))
.getDefaultDisplay();
boolean isWide = d.getWidth() >= d.getHeight();
switch (d.getRotation()) {
case Surface.ROTATION_0:
return isWide ? ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
: ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
case Surface.ROTATION_90:
return isWide ? ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
: ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
case Surface.ROTATION_180:
return isWide ? ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE
: ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
case Surface.ROTATION_270:
return isWide ? ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE
: ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
}
return -1;
}
private void lockOrientation(boolean lock) {
if (lock) {
setRequestedOrientation(getCurentOrientation());
} else {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);
}
}
On 4 devices (2 smartphones and 2 tablets) it works as nedded.
Problem
There is CheckBox with following code: ``` CheckBox cb = (CheckBox)findViewById(R.id.freezer); cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (isChecked) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); } else { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR); } } }); ``` So, when i check it, screen is rotated to default system orientation (landscape for my tablet). I need to freeze CURRENT orientation. If you turned device to portrait and toggled CheckBox, device rotation must be ingored until CheckBox is unchecked. Display.getRotation() is not a solution, because each device has it's own Surface.ROTATION
