MainActivity关键代码:

actionBar=getActionBar();
actionBar.show();

public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}

public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
Resources resources;
Drawable btnDrawable;
item.setChecked(true);
switch (item.getItemId()) {
case R.id.ai1_1:
item.setChecked(true);
resources = getBaseContext().getResources();
btnDrawable = resources.getDrawable(R.drawable.ppp);
V.setBackground(btnDrawable);
break;
case R.id.ai1_2:
item.setChecked(true);
resources = getBaseContext().getResources();
btnDrawable = resources.getDrawable(R.drawable.p2);
V.setBackground(btnDrawable);
break;
case R.id.ai1_3:
item.setChecked(true);
resources = getBaseContext().getResources();
btnDrawable = resources.getDrawable(R.drawable.p4);
V.setBackground(btnDrawable);
break;
case R.id.ai1_4:
item.setChecked(true);
resources = getBaseContext().getResources();
btnDrawable = resources.getDrawable(R.drawable.p3);
V.setBackground(btnDrawable);
break;
case R.id.ai1_5:
item.setChecked(true);
resources = getBaseContext().getResources();
btnDrawable = resources.getDrawable(R.drawable.p5);
V.setBackground(btnDrawable);
break;
case R.id.ai2:
item.setChecked(true);
Intent intent=new Intent();
intent.setClass(MainActivity.this, music_main.class);
startActivity(intent);
break;
case R.id.ai3:
item.setChecked(true);
Intent intent1=new Intent();
intent1.setClass(MainActivity.this, help_main.class);
startActivity(intent1);
break;
case R.id.ai4:
item.setChecked(true);
Intent intent2=new Intent();
intent2.setClass(MainActivity.this, about_main.class);
startActivity(intent2);
case R.id.aix:
item.setChecked(true);
Intent intentx=new Intent();
intentx.setClass(MainActivity.this, newgame_main.class);
startActivity(intentx);

default:
break;
}
return super.onOptionsItemSelected(item);
}

关于、帮助、新游戏关键代码：

ActionBar actionBar;
actionBar=getActionBar();
actionBar.show();
actionBar.setDisplayShowHomeEnabled(true);//显示应用程序图标
actionBar.setDisplayHomeAsUpEnabled(true);

public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
item.setChecked(true);
switch (item.getItemId()) {
case R.id.ai3:
item.setChecked(true);
Intent intent1=new Intent();
intent1.setClass(this, help_main.class);
startActivity(intent1);
finish();
break;
case R.id.ai4:
item.setChecked(true);
Intent intent2=new Intent();
intent2.setClass(this, about_main.class);
startActivity(intent2);
finish();
break;
case android.R.id.home:
item.setChecked(true);
Intent intenth=new Intent(this,MainActivity.class);
//添加额外的Flag，将Activity栈中处于MainActivity之上的Activity弹出
intenth.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Bundle bundle=new Bundle();
bundle.putString("username","");
intenth.putExtras(bundle);
startActivity(intenth);
finish();
break;
case R.id.aix:
item.setChecked(true);
Intent intentx=new Intent();
intentx.setClass(this, newgame_main.class);
startActivity(intentx);
finish();
default:
break;
}
return super.onOptionsItemSelected(item);
}

运行结果：（截图）

如三已展示

五、实验总结（对本实验结果进行分析，实验心得体会及改进意见）

经过实验，熟悉了游戏导航栏设置的基本代码，为游戏增添了方便的操作，是项目更加完整，对于ActionBar的使用，可以应用用于很app，是一个实用的方法。日后还需要提高ActionBar使用的技巧。
