Can't Get Transparent Dialogfragment

I have a dialog Fragment which look like that. AlertDialog ad = builder.create(); Drawable d = new ColorDrawable(Color.BLACK); d.setAlpha(130); ad.getWindow().setBackgroundDrawabl

Solution 1:

The issue is in default dialog theme. Based on this and this answers it's much easier to achieve your target.

The Activity should be like the following:

publicclassMyActivityextendsFragmentActivity {

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main);
    }

    @OverridepublicvoidonBackPressed() {
        MyDialogFragment.newInstance("title title").show(getSupportFragmentManager(), "dialog");
    }
}

And fragment:

publicclassMyDialogFragmentextendsandroid.support.v4.app.DialogFragment {

    /**
     * Create a new instance of MyDialogFragment, providing "title"
     * as an argument.
     */static MyDialogFragment newInstance(String title) {
        MyDialogFragmentfrag=newMyDialogFragment();
        Bundleargs=newBundle();

        args.putString("title", title);
        frag.setArguments(args);
        return frag;
    }

    @Overridepublic Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialogdialog=newDialog(getActivity(),android.R.style.Theme_Translucent_NoTitleBar);
        finalViewview= getActivity().getLayoutInflater().inflate(R.layout.share_or_die, null);

        finalDrawabled=newColorDrawable(Color.BLACK);
        d.setAlpha(130);

        dialog.getWindow().setBackgroundDrawable(d);
        dialog.getWindow().setContentView(view);

        final WindowManager.LayoutParamsparams= dialog.getWindow().getAttributes();
        params.width = WindowManager.LayoutParams.WRAP_CONTENT;
        params.height = WindowManager.LayoutParams.WRAP_CONTENT;
        params.gravity = Gravity.CENTER;

        dialog.setCanceledOnTouchOutside(true);

        return dialog;
    }
}

Also, be sure to do the following: before setContentView() in the activity, getWindow().requestFeature(Window.FEATURE_NO_TITLE) should be added in order to use *NoTitleBar style.

The result is (I've used LinearLayout with single TextView inside):

I hope it can help you

@OverridepublicvoidonStart() {
    super.onStart();

    Windowwindow = getDialog().getWindow();
    WindowManager.LayoutParams windowParams = window.getAttributes();
    windowParams.dimAmount = 0.0f; 

    window.setAttributes(windowParams);
}

None of the above solutions worked for me. What i found to work was to make sure that I had imported android.support.v7.app.AlertDialog instead of the generic app.alertdialog.

Hope this helps others too.

Solution 4:

It works for me:

getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
