关闭DialogFragment后面的click activity？

Question

打开对话框片段时无法取消后台按钮的点击事件。我正在尝试通过另一个片段中的按钮调用对话框片段。

public class DialogPaymentSuccessFragment extends DialogFragment {
private View root_view;
class rootViewClick implements OnClickListener {
    rootViewClick () {
    }

    public void onClick(View view) {
        DialogPaymentSuccessFragment.this.dismiss();
    }
}

public View onCreateView(LayoutInflater layoutInflater, ViewGroup viewGroup, Bundle bundle) {
    this.root_view = layoutInflater.inflate(R.layout.dialog_payment_success, viewGroup, false);
    ((FloatingActionButton) this.root_view.findViewById(R.id.fab)).setOnClickListener(new rootViewClick());
    return this.root_view;
}

@NonNull
public Dialog onCreateDialog(Bundle bundle) {
    bundle = super.onCreateDialog(bundle);
    bundle.requestWindowFeature(1);
    return bundle;
}

public void onDestroyView() {
    super.onDestroyView();
}

}

Answer 1

您可以在 onCreateDialog 方法中设置 cancel able false

像这样

this.setCancelable(false)

Answer 2

如果你定义了rootLayout，你可以禁用layout.You中的所有视图，也可以在打开dialogfragment之前应用activity。

public static void enableDisableView(View view, boolean enabled) {
        view.setEnabled(enabled);
        if ( view instanceof ViewGroup) {
            ViewGroup group = (ViewGroup)view;

            for ( int idx = 0 ; idx < group.getChildCount() ; idx++ ) {
                enableDisableView(group.getChildAt(idx), enabled);
            }
        }
    }

Turn off click activity behind DialogFragment?
