全屏DialogFragment

Question

我试图创建MATCH_PARENT宽度的DialogFragment这样的对话框几乎全屏幕(离开填充周围的边缘为流动的样子).我在Android中看到过这个解决方案Full Screen DialogFragment,但我试图避免将宽度设置为1000dp的黑客攻击.以我目前的布局,我是使用FILL_PARENT或MATCH_PARENT它似乎是设置宽度和高度WRAP_CONTENT.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

我已经将此解决方案用于Dialog(而不是DialogFragment),它按预期工作:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

Answer 1

这对我来说很完美.当扩展DialogFragment 覆盖onCreateView()... impelments所有逻辑

对话框使其全屏只是覆盖此方法

 @Override
public Dialog onCreateDialog(final Bundle savedInstanceState) {

    // the content
    final RelativeLayout root = new RelativeLayout(getActivity());
    root.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

    // creating the fullscreen dialog
    final Dialog dialog = new Dialog(getActivity());
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(root);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.YELLOW));
    dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

    return dialog;
}

Answer 2

尝试切换到RelativeLayout而不是LinearLayout.它适用于我的情况

Answer 3

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NO_TITLE,android.R.style.Theme_Holo_Light);
}
