Note Pad Project (5)
==============

MainActivity ရဲ့ ActionBar ေပၚက + ပံု icon ကို click လုပ္လိုက္ရင္ NoteActivity ပြင့္လာေအာင္ onOptionsItemSelected(...) method ထဲမွာ ဒီလို ေရးပါမယ္။

=========
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if(item.getTitle()=="Add"){
Intent intent=new Intent(this,
NoteActivity.class);
startActivity(intent);
}
return super.onOptionsItemSelected(item);
}
=========
MainActivity.java
=========

package nnl.aide.lessons;

import android.app.*;
import android.os.*;
import android.widget.*;
import android.graphics.drawable.*;
import android.graphics.*;
import android.view.*;
import android.content.*;

public class MainActivity extends Activity
{
ListView lv;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
lv=(ListView)findViewById(R.id.lv);

ActionBar ab=getActionBar();
ab.setBackgroundDrawable(new ColorDrawable(
Color.rgb(255,100,0)));
    }

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
menu.add("Add")
.setIcon(R.drawable.add)
.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if(item.getTitle()=="Add"){
Intent intent=new Intent(this,
NoteActivity.class);
startActivity(intent);
}
return super.onOptionsItemSelected(item);
}
}
=========

NoteActivity.java ဘက္ကို ၀င္ပါ။

Back arrow ပံု နဲ႔ Home Button ကို ႏွိပ္လို႔ ရေအာင္ onCreate ထဲမွာ ဒီလို ေရးပါ။

=========
ab.setHomeButtonEnabled(true);
=========

Arrow ပံု button ကို ႏွိပ္ရင္ NoteActivity ျပန္ပိတ္သြားေအာင္ onOptionsItemSelected(...) method ထဲမွာ ဒီလို ေရးပါ။

=========
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if(item.getItemId()==android.R.id.home){
finish();
}
return super.onOptionsItemSelected(item);
}
=========

NoteActivity.java
==========
package nnl.aide.lessons;
import android.app.*;
import android.widget.*;
import android.os.*;
import android.graphics.drawable.*;
import android.graphics.*;
import android.view.*;

public class NoteActivity extends Activity
{
EditText et;

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.note_layout);
et=(EditText)findViewById(R.id.et);

ActionBar ab=getActionBar();
ab.setBackgroundDrawable(new ColorDrawable(
Color.rgb(255,100,0)));

ab.setHomeButtonEnabled(true);
}

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if(item.getItemId()==android.R.id.home){
finish();
}
return super.onOptionsItemSelected(item);
}
}
==========

Run ၾကည့္ပါ။
