我正在爲一個學校項目製作一個應用程序,並且我卡在一個區域。 我想用一個好的按鈕來解除彈出窗口。 如果您有任何建議或者有更好的方法來實現彈出窗口,請分享它們。如何使用一個好的按鈕來關閉一個Android彈出窗口
package xyz.ashraf.whoisdelasalle;
import android.app.Activity;
import android.os.Bundle;
import android.util.DisplayMetrics;
public class Pop extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.popwindow);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels;
int height = dm.heightPixels;
getWindow().setLayout((int)(width*.8),(int)(height*.5));
}
}
Java代碼^

提前感謝!
爲什麼你使用完整的活動來顯示彈出?您可以改爲使用對話框或彈出窗口,參考這些鏈接http://developer.android.com/guide/topics/ui/dialogs.html http://developer.android.com/reference/android/widget/PopupWindow。 html – HendraWD
