ProgressDialog is not closing with BroadcastReceiver

Question

I am using BroadcatReceiver to monitor wi-fi state changes.

And I want to show ProgressDialog during the operation.

It is showing properly but not closing.

My code is like below::

private final BroadcastReceiver mBluetoothChangeReceiver = new BroadcastReceiver()
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        final String action = intent.getAction();

        if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED))
        {
            final int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, BluetoothAdapter.ERROR);
            switch (state)
            {
            case BluetoothAdapter.STATE_OFF:
                Log.i(TAG, "STATE_OFF");
                showProgress(false);
                // showToast("Bluetooth off");
                break;
            case BluetoothAdapter.STATE_TURNING_OFF:
                Log.i(TAG, "STATE_TURNING_OFF");
                showProgress(true);
                // showToast("Turning Bluetooth off...");
                break;
            case BluetoothAdapter.STATE_ON:
                Log.i(TAG, "STATE_ON");
                showProgress(false);
                // showToast("Bluetooth on");
                break;
            case BluetoothAdapter.STATE_TURNING_ON:
                Log.i(TAG, "STATE_TURNING_ON");
                showProgress(true);
                // showToast("Turning Bluetooth on...");

                break;
            }
        }
    }
};


public void showProgress(boolean show)
{
    ProgressDialog mProgressDialog;
    mProgressDialog = new ProgressDialog(ShortcutActivity.this);

    mProgressDialog.setMessage(mContext.getString(R.string.settings_msg));
    if (show)
    {
        mProgressDialog.setCancelable(false);
        if (!mProgressDialog.isShowing())
            mProgressDialog.show();
    }
    else
    {
        Log.i(TAG, " " + mProgressDialog.isShowing());
        mProgressDialog.setCancelable(true);
        if (mProgressDialog.isShowing())
        {
            mProgressDialog.dismiss();
        }
    }
}`

Please suggest me for solution if my implementation contains any thing wrong. Or my way of implementation was wrong.

Answer 1

1. make the below as global variable

   ProgressDialog mProgressDialog;
   

2. OnCreate()

   mProgressDialog = new ProgressDialog(ShortcutActivity.this);
   mProgressDialog.setMessage(mContext.getString(R.string.settings_msg));
   

3.

private final BroadcastReceiver mBluetoothChangeReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
    final String action = intent.getAction();

    if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED))
    {
        final int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, BluetoothAdapter.ERROR);
        switch (state)
        {
        case BluetoothAdapter.STATE_OFF:
            Log.i(TAG, "STATE_OFF");
            showProgress(false);
            // showToast("Bluetooth off");
            break;
        case BluetoothAdapter.STATE_TURNING_OFF:
            Log.i(TAG, "STATE_TURNING_OFF");
            showProgress(true);
            // showToast("Turning Bluetooth off...");
            break;
        case BluetoothAdapter.STATE_ON:
            Log.i(TAG, "STATE_ON");
            showProgress(false);
            // showToast("Bluetooth on");
            break;
        case BluetoothAdapter.STATE_TURNING_ON:
            Log.i(TAG, "STATE_TURNING_ON");
            showProgress(true);
            // showToast("Turning Bluetooth on...");

            break;
        }
    }
}

};

 public void showProgress(boolean show)
  {

if (show)
{
    mProgressDialog.setCancelable(false);
    if (!mProgressDialog.isShowing())
        mProgressDialog.show();
}
else
{
    Log.i(TAG, " " + mProgressDialog.isShowing());
    mProgressDialog.setCancelable(true);
    if (mProgressDialog.isShowing())
    {
        mProgressDialog.dismiss();
    }
}}
