DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels; //320 dip
int height = dm.heightPixels;
このコードを試しましたが、正しく動作しません。アンドロイドで正しい画面のサイズを取得してください
int width | height = getResources().getDisplayMetrics().widthPixels | heightPixels
や活動の外：
context.getResources().getDisplayMetrics().widthPixels | heightPixels
あなたはすべてのデバイスの密度を持つすべての画面を再生したい場合は、これを試してみてください。..
