Android ProgressBar Creating Custom Progress Dialog
Example
By Creating Custom Progress Dialog class, the dialog can be used to show in UI instance, without recreating the dialog.
First Create a Custom Progress Dialog Class.
CustomProgress.java
public class CustomProgress {
public static CustomProgress customProgress = null;
private Dialog mDialog;
public static CustomProgress getInstance() {
if (customProgress == null) {
customProgress = new CustomProgress();
}
return customProgress;
}
public void showProgress(Context context, String message, boolean cancelable) {
mDialog = new Dialog(context);
// no tile for the dialog
mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
mDialog.setContentView(R.layout.prograss_bar_dialog);
mProgressBar = (ProgressBar) mDialog.findViewById(R.id.progress_bar);
// mProgressBar.getIndeterminateDrawable().setColorFilter(context.getResources()
// .getColor(R.color.material_blue_gray_500), PorterDuff.Mode.SRC_IN);
TextView progressText = (TextView) mDialog.findViewById(R.id.progress_text);
progressText.setText("" + message);
progressText.setVisibility(View.VISIBLE);
mProgressBar.setVisibility(View.VISIBLE);
// you can change or add this line according to your need
mProgressBar.setIndeterminate(true);
mDialog.setCancelable(cancelable);
mDialog.setCanceledOnTouchOutside(cancelable);
mDialog.show();
}
public void hideProgress() {
if (mDialog != null) {
mDialog.dismiss();
mDialog = null;
}
}
}
Now creating the custom progress layout
prograss_bar_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="65dp"
android:background="@android:color/background_dark"
android:orientation="vertical">
<TextView
android:id="@+id/progress_text"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_above="@+id/progress_bar"
android:layout_marginLeft="10dp"
android:layout_marginStart="10dp"
android:background="@android:color/transparent"
android:gravity="center_vertical"
android:text=""
android:textColor="@android:color/white"
android:textSize="16sp"
android:visibility="gone" />
<-- Where the style can be changed to any kind of ProgressBar -->
<ProgressBar
android:id="@+id/progress_bar"
style="@android:style/Widget.DeviceDefault.ProgressBar.Horizontal"
android:layout_width="match_parent"
android:layout_height="30dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_gravity="center"
android:background="@color/cardview_dark_background"
android:maxHeight="20dp"
android:minHeight="20dp" />
</RelativeLayout>
This is it. Now for calling the Dialog in Code
CustomProgress customProgress = CustomProgress.getInstance();
// now you have the instance of CustomProgres
// for showing the ProgressBar
customProgress.showProgress(#Context, getString(#StringId), #boolean);
// for hiding the ProgressBar
customProgress.hideProgress();
