Android 教程 使用Service

核心提示：_boundService = null;Toast.makeText(TestServiceHolder.this, “Service connected”,Toast.LENGTH_SHORT).show();}};private void initButtons() {Button buttonStart = (

_boundService = null;

Toast.makeText(TestServiceHolder.this, “Service connected”,

Toast.LENGTH_SHORT).show();

}

};

private void initButtons() {

Button buttonStart = (Button) findViewById(R.id.start_service);

buttonStart.setOnClickListener(new OnClickListener() {

public void onClick(View arg0) {

startService();

}

});

Button buttonStop = (Button) findViewById(R.id.stop_service);

buttonStop.setOnClickListener(new OnClickListener() {

public void onClick(View arg0) {

stopService();

}

});

Button buttonBind = (Button) findViewById(R.id.bind_service);

buttonBind.setOnClickListener(new OnClickListener() {

public void onClick(View arg0) {

bindService();

}

});

Button buttonUnbind = (Button) findViewById(R.id.unbind_service);

buttonUnbind.setOnClickListener(new OnClickListener() {

public void onClick(View arg0) {

unbindService();

}

});

}

private void startService() {

Intent i = new Intent(this, TestService.class);

this.startService(i);

}

private void stopService() {

Intent i = new Intent(this, TestService.class);

this.stopService(i);

}

private void bindService() {

Intent i = new Intent(this, TestService.class);

bindService(i, _connection, Context.BIND_AUTO_CREATE);

_isBound = true;

}

private void unbindService() {

if (_isBound) {

unbindService(_connection);

_isBound = false;

}

}

}

这里可以看到两种启动方法，start和bind，当然也是通过intent调用的，在intent中指明指定要启动的Service的名字，stop也一样
