</GridLayout>
Step 3 : Open src -> package -> MainActivity.java and add following code :
package com.gudivada.hemanthsomaraju;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
TextView t1, t2, t3, t4, t5, t6, t7, t8, t9;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
t1 = (TextView) findViewById(R.id.text1);
t2 = (TextView) findViewById(R.id.text2);
t3 = (TextView) findViewById(R.id.text3);
t4 = (TextView) findViewById(R.id.text4);
t5 = (TextView) findViewById(R.id.text5);
t6 = (TextView) findViewById(R.id.text6);
t7 = (TextView) findViewById(R.id.text7);
t8 = (TextView) findViewById(R.id.text8);
t9 = (TextView) findViewById(R.id.text9);
t1.setClickable(true);
t2.setClickable(true);
t3.setClickable(true);
t4.setClickable(true);
t5.setClickable(true);
t6.setClickable(true);
t7.setClickable(true);
t8.setClickable(true);
t9.setClickable(true);
t1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[0,0] Clicked",
Toast.LENGTH_SHORT).show();
}
});
t2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[0,1] Clicked",
Toast.LENGTH_SHORT).show();
}
});
t3.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[0,2] Clicked",
Toast.LENGTH_SHORT).show();
}
});
t4.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[1,0] Clicked",
Toast.LENGTH_SHORT).show();
}
});
t5.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[1,1] Clicked",
Toast.LENGTH_SHORT).show();
}
});
t6.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[1,2] Clicked",
Toast.LENGTH_SHORT).show();
}
});
t7.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[2,0] Clicked",
Toast.LENGTH_SHORT).show();
}
});
t8.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[2,1] Clicked",
Toast.LENGTH_SHORT).show();
}
});
t9.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "[2,2] Clicked",
Toast.LENGTH_SHORT).show();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Step 4 : Open AndroidManifest.xml and add following code :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.gudivada.hemanthsomaraju"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.gudivada.hemanthsomaraju.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
