Hello Friends !
    This is a very useful demo for how to create Alert Dialog Box or Confirmation Box in Android.

1-PrintScreen:



2-AlertDialogActivity.java

package com.manish.dialogbox;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class AlertDialogActivity extends Activity {

       /** Called when the activity is first created. */
       @Override
       public void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.main);
              Button btn = (Button) findViewById(R.id.button1);
              btn.setOnClickListener(new OnClickListener() {

                     @Override
                     public void onClick(View v) {
                           // TODO Auto-generated method stub
                           alertMessage();
                     }
              });
       }

       public void alertMessage() {
              DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
                     public void onClick(DialogInterface dialog, int which) {
                           switch (which) {
                           case DialogInterface.BUTTON_POSITIVE:
                                  // Yes button clicked
                                  Toast.makeText(AlertDialogActivity.this, "Yes Clicked",
                                                Toast.LENGTH_LONG).show();
                                  break;

                           case DialogInterface.BUTTON_NEGATIVE:
                                  // No button clicked
                                  // do nothing
                                  Toast.makeText(AlertDialogActivity.this, "No Clicked",
                                                Toast.LENGTH_LONG).show();
                                  break;
                           }
                     }
              };

              AlertDialog.Builder builder = new AlertDialog.Builder(this);
              builder.setMessage("Are you sure?")
                           .setPositiveButton("Yes", dialogClickListener)
                           .setNegativeButton("No", dialogClickListener).show();
       }
}

    1. Do something like that-
      On delete button click just call a method with-
      if (v == btnErase) {
      eraseConfirmation(5);
      }

      And your Method should be like-
      public void eraseConfirmation(int id){
      DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int which) {
      switch (which){
      case DialogInterface.BUTTON_POSITIVE:
      //Yes button clicked
      //delete here what you want with your id
      break;
      case DialogInterface.BUTTON_NEGATIVE:
      //No button clicked
      //do nothing
      break;
      }
      }
      };
      AlertDialog.Builder builder = new AlertDialog.Builder(this);
      builder.setMessage("Are you sure?").setPositiveButton("Yes", dialogClickListener)
      .setNegativeButton("No", dialogClickListener).show();
      }

      It should work for you...
      And if your view is not update automatic please call onResume() method...

  6. Nice tutorial Manish, Thanks for writing it.
    San you please help me for this extended functionality:
    How can we return a flag like true on Yes click , false on No click so that I can reuse this confirm box in my application

    All I need is:
    1 having a row with data and a delete button
    2. on click of delete button-> confirm box should open
    3. if yes is clicked then remove the entire row
    4. else do nothing

    So My idea is to reuse this confirm box for "delete/edit" many more other functionality.

    ReplyDelete
  8. Actually Dialog button don't have more then 2 button. For this you can create Popup window and create how many button you want. You can check my blog for popup window..

    package com.ilmnuri.com.adapter;

    import android.content.Context;
    import android.content.Intent;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.BaseAdapter;
    import android.widget.ImageButton;
    import android.widget.ImageView;
    import android.widget.RelativeLayout;
    import android.widget.TextView;

    import com.ilmnuri.com.PlayActivity;
    import com.ilmnuri.com.R;
    import com.ilmnuri.com.Utility.Utils;
    import com.ilmnuri.com.model.AlbumModel;
    import com.ilmnuri.com.model.Api;

    public AlbumAdapter (Context context, AlbumModel albumModel) {
    this.context = context;

    @Override
    public Object getItem(int position) {
    return null;
    }

    @Override
    public long getItemId(int position) {
    return 0;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {

    View v = convertView;
    if (convertView == null) {
    v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_album, null);
    }
    RelativeLayout relativeLayout = (RelativeLayout)v.findViewById(R.id.rl_item_album);
    TextView textView = (TextView)v.findViewById(R.id.tv_item_album);
    ImageView imageView = (ImageView)v.findViewById(R.id.iv_item_album);
    ImageButton btnDelete = (ImageButton)v.findViewById(R.id.btn_delete);

    textView.setText(albumModel.getArrTrack().get(position).replace(".mp3", "").replace("_", " "));
    if (Utils.checkFileExist(Api.localPath + "/" + albumModel.getArrTrack().get(position))) {
    btnDelete.setVisibility(View.VISIBLE);

    intent.putExtra("category", albumModel.getCategory());
    intent.putExtra("url",albumModel.getCategory() + "/" + albumModel.getAlbum() + "/" + albumModel.getArrTrack().get(position));
    context.startActivity(intent);
    }
    });
    btnDelete.setOnClickListener(new View.OnClickListener() {
    @Override

    Utils.deleteFile(Api.localPath + "/" + albumModel.getArrTrack().get(position));
    notifyDataSetChanged();
    }
    });
    return v;
    }


    }

    1. 1)Put alert method inside click event-
      btnDelete.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
      alertMessage();
      }
      });

      2)now write your delete code inside positive button-

      public void alertMessage() {
      DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int which) {
      switch (which) {
      case DialogInterface.BUTTON_POSITIVE:
      // Yes button clicked
      Utils.deleteFile(Api.localPath + "/" + albumModel.getArrTrack().get(position));
      notifyDataSetChanged();

      break;

      case DialogInterface.BUTTON_NEGATIVE:
      // No button clicked
      // do nothing
      Toast.makeText(AlertDialogActivity.this, "No Clicked",
      Toast.LENGTH_LONG).show();
      break;
      }
      }
      };

      AlertDialog.Builder builder = new AlertDialog.Builder(this);
      builder.setMessage("Are you sure?")
      .setPositiveButton("Yes", dialogClickListener)
      .setNegativeButton("No", dialogClickListener).show();
      }

    4. Just pass the "context" instead of "this".
