[ACCEPTED]-Android Activity Indicator?-android-activity

The most direct equivalent of the iOS Activity 6 Indicator in Android is the ProgressBar but set to 5 indeterminate. So you can drop the view 4 into your layout and it will provide you 3 with a spinning animation.

<ProgressBar
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:id="@+id/ctrlActivityIndicator"
    android:indeterminateOnly="true"
    android:keepScreenOn="true"
     />

You could use 2 this to indicate some background activity 1 to the user.

do some thing like this

ProgressDialog mDialog = new ProgressDialog(getApplicationContext());
            mDialog.setMessage("Please wait...");
            mDialog.setCancelable(false);
            mDialog.show();

There are two other ways of showing activity 7 indicator without using modal ProgressDialog.

You 6 can use ImageView in your layout and apply 5 animation to it. Refer developer's site.

public void startAnimation() {
  // Create an animation
  RotateAnimation rotation = new RotateAnimation(
      0f,
      360f,
      Animation.RELATIVE_TO_SELF,
      0.5f,
      Animation.RELATIVE_TO_SELF,
      0.5f);
  rotation.setDuration(1200);
  rotation.setInterpolator(new LinearInterpolator());
  rotation.setRepeatMode(Animation.RESTART);
  rotation.setRepeatCount(Animation.INFINITE);

  // and apply it to your imageview
  findViewById(R.id.myActivityIndicator).startAnimation(rotation);
}

Or you can use xml-drawable 4 to describe a background image, which will 3 have some rotating animation:

Firstly describe 2 a drawable (in i.e. /res/drawable/my-indicator.xml)

<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/spinner_black_76"
    android:pivotX="50%"
    android:pivotY="50%"
    android:framesCount="12"
    android:frameDuration="100" />

Then 1 set it at some view's background

public class Mp3cutterActivity extends Activity {

    MP3Class mp3obj = null;
    TextView tv;
    MP3Class mp3classobj = null;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Context thiscontext = this.getApplicationContext();
        mp3classobj = new MP3Class(thiscontext);
        setContentView(R.layout.main);

        Button btn = (Button)findViewById(R.id.startbutton);
        tv = (TextView)findViewById(R.id.textview1);
        btn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                //show a wait indicator as well as the function that calls walkSdcard

                try {
                    new SearchSdCard(Mp3cutterActivity.this).execute();
                    // copyProtector.doCopyProtection();
                } catch (Exception e) {
                    System.out.println("in search SD card  " + e.getMessage());
                }
            }

            private void domp3stuff() {
                // TODO Auto-generated method stub
            }
        });
    }
}

class SearchSdCard extends AsyncTask<String, Void, Boolean> {

    Context context;    

    public ProgressDialog dialog;

    public SearchSdCard(Activity activity) {
        this.context = activity;
    }

    protected void onPreExecute() {
        dialog = new ProgressDialog(context);
        dialog.setMessage("wait for a moment...");
        dialog.show();
    }

    @Override
    protected Boolean doInBackground(String... params) {
        // TODO Auto-generated method stub
        boolean retval = true;
        mp3classobj.searchSdCard();
        return retval;
    }

    @Override
    protected void onPostExecute(Boolean result) {
        // TODO Auto-generated method stub
        if (dialog.isShowing()) {
            dialog.dismiss();
            tv.setText("mp3 cutter is an app which cuts down a chunk of memory \nfrom your sdcard by \ndeleting the .mp3 files and more \nyou were made a BAKRA :-)");
            if(!result){    
                tv.setText("error occured !!");
            }
        }
    }
    //refer below comment for the MP3class.java file details
}

Activity indicator is nothing but it is 6 known as progress dialog. You can create 5 programmatically.Numbers of tutorials are 4 available, Search how to create progress 3 dialog/ProgressBar

ProgressDialog progressDialog = new ProgressDialog(MainActivity.this);
                progressDialog.setMax(100);
                progressDialog.setMessage("Its loading....");
                progressDialog.setTitle("ProgressDialog bar example");
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
or
progressDialog.setProgressStyle(ProgressDialog.STYLE_CIRCULAR);

or you can create it by 2 using xml , set the visibility visible once task 1 get completed set visibility gone

<ProgressBar
                android:id="@+id/loading_spinner"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginTop="100dp"
                android:indeterminateTintMode="src_atop"
                android:indeterminateTint="@color/grey"
                android:layout_gravity="center" />
