Android:如何将dialogFragment设置为全屏

Question

您好我试图将该主题覆盖到dialogFragment全屏,但我想要的全屏是上一个活动的叠加层,所以当打开dialogFragment时,我们仍然可以看到屏幕和dialogFragment之间填充的活动.

这是我用于全屏的风格

<style name="fullscreen_dialog" parent="android:Theme" >
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowIsFloating">false</item>
</style>

Answer 1

这是我想出来处理你的问题的解决方案:

@Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);    
        dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        return dialog;
    }

    @Override
    public void onStart() {
        super.onStart();
        Dialog dialog = getDialog();
        if (dialog != null) {
           dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        }
    }

以下解决方案适合我.

为Fragment Dialog创建样式,如下所示:

<style name="dialog_theme" parent="android:Theme" >
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">false</item>
</style>

创建您的java类如下:

public class FiltersDialogFragment extends android.support.v4.app.DialogFragment {

    static FiltersDialogFragment newInstance() {
        FiltersDialogFragment fragment = new FiltersDialogFragment();
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(DialogFragment.STYLE_NORMAL, R.style.dialog_theme);
    }

    @Override
    public void onStart() {
        super.onStart();
        Dialog d = getDialog();
        if (d!=null){
            int width = ViewGroup.LayoutParams.MATCH_PARENT;
            int height = ViewGroup.LayoutParams.MATCH_PARENT;
            d.getWindow().setLayout(width, height);
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.dialog_filters, container, false);
        return view;
    }
}

快乐的编码!

你也可以这样做 -

@Override
  public void onCreate(@Nullable final Bundle savedInstanceState) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      setStyle(STYLE_NO_TITLE, android.R.style.Theme_Material_Light_NoActionBar_Fullscreen);
    } else {
      setStyle(STYLE_NO_TITLE, android.R.style.Theme_DeviceDefault_Light_NoActionBar);
    }
    super.onCreate(savedInstanceState);

  }

您可以像这样在代码中手动设置布局参数。希望能帮助到你 ！:)。另请检查此SO调整android中自定义对话框的大小

Window window = myDialog.getWindow();
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
