Part 2: inserting data into tables
</manifest>
ScreenShots:
Step 1: add the following method in DBAdapter
DBAdapter.java
public long insertValues(String
name, String contact) {
ContentValues
values = new ContentValues();
values.put("name", name);
values.put("phone", contact);
return database.insert(DBOpenHelper.SAMPLE_TABLE_NAME, null, values);
}
Step 2: Create InsertActivity and its respective xml write
the following code in xml and Activity
activity_insert.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".InsertActivity" >
<EditText
android:id="@+id/insert_editText_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:ems="10"
android:hint="Enter Your Name" >
<requestFocus />
</EditText>
<EditText
android:id="@+id/insert_editText_contact"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/insert_editText_name"
android:layout_below="@+id/insert_editText_name"
android:layout_marginTop="20dp"
android:ems="10"
android:hint="Enter Your Contact Number"
android:inputType="phone" />
<Button
android:id="@+id/insert_button_submit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/insert_editText_contact"
android:layout_below="@+id/insert_editText_contact"
android:layout_marginLeft="10dp"
android:layout_marginTop="24dp"
android:text="Submit"
android:onClick="submit" />
<Button
android:id="@+id/insert_button_cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/insert_button_submit"
android:layout_alignRight="@+id/insert_editText_contact"
android:layout_marginRight="10dp"
android:text="Cancel"
android:onClick="cancel" />
</RelativeLayout>
InsertActivity.java
package
com.swamys.databaseexample;
import
android.app.Activity;
import android.os.Bundle;
import android.view.View;
import
android.widget.EditText;
import
android.widget.Toast;
import
com.swamys.database.dbadapter.DBAdapter;
public class InsertActivity extends Activity {
EditText
editText_name, editText_contact;
String
name, contact;
DBAdapter
dbAdapter;
@Override
protected void onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_insert);
// create
references for all the four views
editText_name = (EditText)
findViewById(R.id.insert_editText_name);
editText_contact = (EditText)
findViewById(R.id.insert_editText_contact);
// create reference
for DBAdaper
dbAdapter = new
DBAdapter(getApplicationContext());
}
// submit button
click listener
public void submit(View view) {
name = editText_name.getText().toString();
contact = editText_contact.getText().toString();
long response = dbAdapter.insertValues(name, contact);
if (response == -1) {
Toast.makeText(getApplicationContext(),
"Data
failed to insert",
Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(getApplicationContext(),
"Data inserted
successfully", Toast.LENGTH_LONG).show();
}
finish();
}
// cancel button
click listener
public void cancel(View view) {
finish();
}
@Override
protected void onDestroy() {
super.onDestroy();
dbAdapter.closeConnection();
}
}
Step 3: create button in activity_main.xml name it as insert
activity_main.xml
<Button
android:id="@+id/main_button_insert"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="18dp"
android:text="Insert"
android:onClick="insert" />
Step 4: add insert(View) method in MainActivity
MainActivity.java
public void insert(View view) {
Intent
intent = new Intent(getApplicationContext(),
InsertActivity.class);
startActivity(intent);
}
Step 5: Register InsertActivity in Manifest file
Manifest.xml
<?xml version="1.0"
encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.swamys.databaseexample"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.swamys.databaseexample.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN"
/>
<category android:name="android.intent.category.LAUNCHER"
/>
</intent-filter>
</activity>
<activity
android:name="com.swamys.databaseexample.InsertActivity"
android:label="@string/title_activity_insert"
>
</activity>
</application>
