Showing Toast in Android

Toast is very good solution when need to notify user about something.

For example I always show Toast to the user when it wants to open SDCard which is not mounted (best practice).

I am going to show simple Toast which shows on the center of activity. Please check all methods,you will find a lot of interesting.

Toast msg = Toast.makeText(Main.this,"Message",Toast.LENGTH_LONG);msg.setGravity(Gravity.CENTER,msg.getXOffset() / 2,msg.getYOffset() / 2);msg.show();

Interesting method is makeText. 3-rd parameter represents how long should be showed Toast.

Example:

import android.app.Activity;import android.os.Bundle;import android.view.Gravity;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Toast;public class Main extends Activity{ private Button clickBtn; @Override  public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.main); clickBtn = (Button) findViewById(R.id.click); clickBtn.setText("Show message"); clickBtn.setOnClickListener(new OnClickListener(){ @Override  public void onClick(View v){Toast msg = Toast.makeText(Main.this,"Message",Toast.LENGTH_LONG);msg.setGravity(Gravity.CENTER,msg.getXOffset() / 2,msg.getYOffset() / 2);msg.show(); }  }); }}

Showing notification such this one is very good practice. I am sure that it is useful approach.
