Android 2.3.3
I have a progressdialog that shows, Loading.. as text. Here is the code for the progressdialog .
progressDialog = new ProgressDialog(mContext);
progressDialog.setIndeterminate(true);
progressDialog.setMessage("Loading...");
progressDialog.show();
If I remove the line progressDialog.setMessage("Loading...");, I get a progressdialog of the left and an empty box on the right that occupies the width of the parent.
I want to display only the progressdialog , aligned at the center. Please refer to the images below..
This is what i have...
This is what i want...
Can someone help me with this?
Try this 1.create a method like this :
public static ProgressDialog createProgressDialog(Context context) {
ProgressDialog dialog = new ProgressDialog(context);
try {
dialog.show();
} catch (BadTokenException e) {
}
dialog.setCancelable(false);
dialog.getWindow()
.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.setContentView(R.layout.progressdialog);
// dialog.setMessage(Message);
return dialog;
}
// Xml Layout :
<?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="wrap_content"
android:layout_gravity="center"
android:background="@android:color/transparent" >
<ProgressBar
android:id="@+id/progressBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
</RelativeLayout>
and call this method wherever you want :
if (progressDialog == null) {
progressDialog = Utils.createProgressDialog(Login.this);
progressDialog.show();
} else {
progressDialog.show();
}
If you happen to get the error : "requestFeature() must be called before adding content", the solution is to call progressDialog.show() BEFORE you call progressDialog.setContentView(R.layout.progressdialog).
you can add below style in your style.xml
<style name="progress_bar_style">
<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>
where you add any color in color.xml file.
Working and looking good on material design with accent color (if you have them)
Tried hard to make it work on both 5.0+ and lower API version. And the solution is to make it with a dialog instead of a progress.
in layout folder create a file aux_progress_spinner.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:background="@android:color/transparent"
android:gravity="center"
android:orientation="vertical" >
<ProgressBar
android:id="@+id/progressBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@android:color/transparent"
/>
</LinearLayout>
Create a function somewhere...let's say Utils.class
public static Dialog LoadingSpinner(Context mContext){
Dialog pd = new Dialog(mContext, android.R.style.Theme_Black);
View view = LayoutInflater.from(mContext).inflate(R.layout.aux_progress_spinner, null);
pd.requestWindowFeature(Window.FEATURE_NO_TITLE);
pd.getWindow().setBackgroundDrawableResource(R.color.transparent);
pd.setContentView(view);
return pd;
}
In your fragment/activity call:
private Dialog progress_spinner;
progress_spinner = Utils.LoadingSpinner(mContext);
//------ Where you want it ------
progress_spinner.show();
//------- Dismiss it --------
progress_spinner.dismiss();
Optional: add a simple CountDownTimer to test how it looks
new CountDownTimer(1000,1000){
@Override public void onTick(long millisUntilFinished) {
}
@Override public void onFinish() {
progress.dismiss();
}
}.start();
You can use:
Progress progress = new ProgressDialog(getActivity(), android.support.v4.app.DialogFragment.STYLE_NO_TITLE);
If necessary, add to Gradle dependencies
compile 'com.android.support:support-v4:22.2.0'
Use ProgressBar instead of ProgressDialog. http://developer.android.com/reference/android/widget/ProgressBar.html
you can use :
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
and if you want no title you can :
progressDialog.setTitle(null);
MuraliGanesan's answer is correct, but I use just Dialog, not ProgressDialog to avoid "requestFeature() must be called before adding content" exception
You can do this by just creating one class which extends Dialog class:
Let's say I have created below class:
public class TransparentProgressDialog extends Dialog {
public ImageView iv;
public TransparentProgressDialog(Context context, int resourceIdOfImage) {
super(context, R.style.TransparentProgressDialog);
WindowManager.LayoutParams wlmp = getWindow().getAttributes();
wlmp.gravity = Gravity.CENTER_HORIZONTAL;
getWindow().setAttributes(wlmp);
setTitle(null);
setCancelable(false);
setOnCancelListener(null);
LinearLayout layout = new LinearLayout(context);
layout.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
iv = new ImageView(context);
iv.setImageResource(resourceIdOfImage);
layout.addView(iv, params);
addContentView(layout, params);
}
@Override
public void show() {
super.show();
RotateAnimation anim = new RotateAnimation(0.0f, 360.0f , Animation.RELATIVE_TO_SELF, .5f, Animation.RELATIVE_TO_SELF, .5f);
anim.setInterpolator(new LinearInterpolator());
anim.setRepeatCount(Animation.INFINITE);
anim.setDuration(3000);
iv.setAnimation(anim);
iv.startAnimation(anim);
}
}
Put TransparentProgressDialog in style.xml:
@null @android:color/transparent true @null @null @android:style/Animation.Dialog stateUnspecified|adjustPan true @android:color/transparent
Now you can put any progress image which will circulate:
TransparentProgressDialog pDialog = new TransparentProgressDialog(mContext, R.drawable.progress);
pDialog.show();
That's it.
This work for me in MonoDroid:
progressDialog.SetMessage((string)null);
Try this in java:
progressDialog.setMessage(null);
Based on MuraliGanesan answer I created a subclass of progressDialog.
public class LoadingDialog extends ProgressDialog {
public LoadingDialog(Context context) {
super(context);
}
@Override
public void show() {
super.show();
setCancelable(false);
getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
setContentView(R.layout.custom_progress_dialog);
}
}
Also you have to create the custom_progress_dialog.xml in res/layout
<?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="wrap_content"
android:background="@android:color/transparent"
android:layout_gravity="center">
<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
</RelativeLayout>
And you use it as easy as this:
LoadingDialog dialog = new LoadingDialog(this);
dialog.show();
:
:
dialog.dismiss();
ProgressDialog.show(this, null,"", true);
