layout_width - layout android

getSize() me da errores

Question

Cuando implemento

WindowManager wm = ((WindowManager)context.getSystemService(context.WINDOW_SERVICE));
Display display = wm.getDefaultDisplay();
m_nDisplayWidth = display.getWidth();
m_nDisplayHeight = display.getHeight();

Puedo ejecutar bien, pero cuando implemento getSize obtengo runtimeError

Point size = new Point();
display.getSize(size); //Error right here
m_nDisplayWidth = size.x;
m_nDisplayHeight = size.y;

Answer 1

Aquí está el método de utilidad, podría utilizar:

public static int getWidth(Context context) {
WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Display display = windowManager.getDefaultDisplay();
Point size = new Point();
int width;
if (Build.VERSION.SDK_INT >= 13) {
display.getSize(size);
width = size.x;
} else {
width = display.getWidth();
}
return width;
}

Answer 2

Esta versión también funciona para API <4:

@SuppressWarnings("deprecation")
@TargetApi(VERSION_CODES.HONEYCOMB_MR2)
public static Point getSize(Display display) {
Point point = new Point();
if (sdkInt() >= VERSION_CODES.HONEYCOMB_MR2) {
display.getSize(point);
} else {
point.set(display.getWidth(), display.getHeight());
}
return point;
}
@SuppressWarnings("deprecation")
public static int sdkInt() {
return Integer.parseInt(VERSION.SDK);
}

Answer 3

Esto es compatible con dispositivos más antiguos y más nuevos:

private static Point getDisplaySize(final Display display) {
final Point point = new Point();
try {
display.getSize(point);
} catch (java.lang.NoSuchMethodError ignore) { // Older device
point.x = display.getWidth();
point.y = display.getHeight();
}
return point;
}

Answer 4

Intenta esto, funciona para mí.

getWindowManager().getDefaultDisplay().getWidth();

Answer 5

Lo siento, llego tarde a la fiesta, pero asegúrate de que estés usando Android sdk 13 o superior.

Answer 6

Método para obtener el tamaño de pantalla para todos los dispositivos:

private static Point getDisplaySize(final Display display) {
Point point = new Point();
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2){ //API LEVEL 13
display.getSize(point);
}else{
point.x = display.getWidth();
point.y = display.getHeight();
}
return point;
}

Obtención de tamaño:

 WindowManager wm = ((WindowManager)context.getSystemService(context.WINDOW_SERVICE));
Display display = wm.getDefaultDisplay();
Point myPoint = getDisplaySize(display);
Log.i("***Size X::", String.valueOf(myPoint.x));
Log.i("***Size Y::", String.valueOf(myPoint.y));

Answer 7

Trate de usar eso en su lugar:

Display display = getWindowManager().getDefaultDisplay();

Sin eso, no veo ningún problema en este código ...
