Przy pisaniu aplikacji wymuszających tryb pełnoekranowy także po uruchomieniu (ionic.Platform.isFullScreen = true
) może pojawić się problem z przycinaniem contentu przy widocznej klawiaturze. Problem konkretnie na urządzeniach z systemem Android.
Obejściem problemu jest modyfikacja kodu wtyczki (./plugins/ionic-plugin-keyboard/src/android/IonicKeyboard.java
):
if ("init".equals(action)) {
cordova.getThreadPool().execute(new Runnable() {
public void run() {
//calculate density-independent pixels (dp)
//http://developer.android.com/guide/practices/screens_support.html
DisplayMetrics dm = new DisplayMetrics();
cordova.getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);
final float density = dm.density;
final int densityDpi = dm.densityDpi;
//http://stackoverflow.com/a/4737265/1091751 detect if keyboard is showing
final View rootView = cordova.getActivity().getWindow().getDecorView().findViewById(android.R.id.content).getRootView();
OnGlobalLayoutListener list = new OnGlobalLayoutListener() {
int previousHeightDiff = 0;
@Override
public void onGlobalLayout() {
Rect r = new Rect();
//r will be populated with the coordinates of your view that area still visible.
rootView.getWindowVisibleDisplayFrame(r);
PluginResult result;
int statusHeight = 0;
if (densityDpi >= 240)
statusHeight = (int)(38 * density);
else if (densityDpi >= 160)
statusHeight = (int)(25 * density);
else
statusHeight = (int)(19 * density);
int heightDiff = rootView.getRootView().getHeight() - r.bottom + statusHeight;
int pixelHeightDiff = (int)(heightDiff / density);
if (pixelHeightDiff > 100 && pixelHeightDiff != previousHeightDiff) { // if more than 100 pixels, its probably a keyboard...
String msg = "S" + Integer.toString(pixelHeightDiff);
result = new PluginResult(PluginResult.Status.OK, msg);
result.setKeepCallback(true);
callbackContext.sendPluginResult(result);
}
else if ( pixelHeightDiff != previousHeightDiff && ( previousHeightDiff - pixelHeightDiff ) > 100 ){
String msg = "H";
result = new PluginResult(PluginResult.Status.OK, msg);
result.setKeepCallback(true);
callbackContext.sendPluginResult(result);
}
previousHeightDiff = pixelHeightDiff;
}
};
rootView.getViewTreeObserver().addOnGlobalLayoutListener(list);
PluginResult dataResult = new PluginResult(PluginResult.Status.OK);
dataResult.setKeepCallback(true);
callbackContext.sendPluginResult(dataResult);
}
});
return true;
}
