How to center progress indicator in ProgressDialog easily (when no title/text passed along)

Question

When calling progressDialog = ProgressDialog.show(this, null, null, true); usually the developers wants to only show the progress indication image, and usually

Answer 1

You can always add one ProgressBar in all your activities where you might want to show centered ProgressDialog. Use following in acitivity.xml As:

<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content" 
android:id="@+id/progressBar"
android:layout_centerInParent="true"
android:visibility="gone"/>

In your Acitivity.java, use

ProgressBar bar = new Progress();
bar = (ProgressBar) findViewById(R.id.progressBar);

Now when you want to show the ProgressBar, just set its visibility to visible, and to cancel, set visibility to gone.

bar.setVisibility(View.VISIBLE);
bar.setVisibility(View.GONE);

Answer 2

If you want to display indeterminate progress bar only.

ProgressDialog progressDialog = ProgressDialog.show(this, null, null, true, false);
progressDialog.setContentView(R.layout.progress_layout);

And create a layout xml file with name "progress_layout.xml"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ProgressBar
        android:id="@+id/progressBar1"
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" />

</LinearLayout>

Answer 3

Just Do The Below Method To Get It Done

In res->values->styles add the below code

<style name="MyGravity" parent="android:Theme.Material.Dialog" ></style>

Then create yours ProgressDialog as mentioned below

ProgressDialog dialog = new ProgressDialog(ctx, R.style.MyGravity);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);

Answer 4

I did some testing and I feel that the best way to achieve this is doing a custom Dialog.

Here is an example of what I did. This will answer question number 2 but will give you an idea of how to fix question number 1.

public class MyProgressDialog extends Dialog {

    public static MyProgressDialog show(Context context, CharSequence title,
            CharSequence message) {
        return show(context, title, message, false);
    }

    public static MyProgressDialog show(Context context, CharSequence title,
            CharSequence message, boolean indeterminate) {
        return show(context, title, message, indeterminate, false, null);
    }

    public static MyProgressDialog show(Context context, CharSequence title,
            CharSequence message, boolean indeterminate, boolean cancelable) {
        return show(context, title, message, indeterminate, cancelable, null);
    }

    public static MyProgressDialog show(Context context, CharSequence title,
            CharSequence message, boolean indeterminate,
            boolean cancelable, OnCancelListener cancelListener) {
        MyProgressDialog dialog = new MyProgressDialog(context);
        dialog.setTitle(title);
        dialog.setCancelable(cancelable);
        dialog.setOnCancelListener(cancelListener);
        /* The next line will add the ProgressBar to the dialog. */
        dialog.addContentView(new ProgressBar(context), new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        dialog.show();

        return dialog;
    }

    public MyProgressDialog(Context context) {
        super(context, R.style.NewDialog);
    }
}

All the static methods comes from this link, nothing strange, but the magic occurs in the constructor. Check that I pass as parameter an style. That style is the following:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="NewDialog" parent="@android:Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowTitleStyle">@null</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
        <item name="android:backgroundDimEnabled">false</item>
        <item name="android:background">@android:color/transparent</item>
    </style>
</resources>

The result of this is a ProgressBar rotating in the center of the screen. Without backgroundDim and without the Dialog box.

Easy and customizable way:

Define animation: (res/drawable/loader_anim.xml)

<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@drawable/image_for_rotation"
android:pivotX="50%"
android:pivotY="50%" />

or:

<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:drawable="@drawable/img_loader_frame1"
android:duration="150"/>
...
<item
android:drawable="@drawable/img_loader_frame2"
android:duration="150"/>
...
</animation-list>

then, define layout: (res/layout/loader.xml)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="center_vertical|center_horizontal"> 
<ProgressBar
android:layout_width="200dp"
android:layout_height="200dp"
android:indeterminateDrawable="@drawable/loader_anim" />
</LinearLayout>

and then, instance progress dialog:

ProgressDialog dialog;
...
dialog = ProgressDialog.show(this,null,null);
dialog.setContentView(R.layout.loader);
...
process();
...
dialog.dismiss();

Using ProgressBar and adding it to LinearLayout worked in my Case as follows:

ProgressBar mSpinner = new ProgressBar(this); 
mSpinner.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
mSpinner.setBackgroundResource(R.drawable.loading_1);
mSpinner.setIndeterminate(true);
