你好我正在使用android服务。我使用此示例Android Speech Recognition as a service on Android 4.1 & 4.2创建了一个服务，它工作正常，但现在我想发送一些数据，以便服务可以使用新设置运行，但我不知道如何做到这一点我已经使用了getExtra但是我无法使用以前的设置终止服务并以新设置开始。 这是我的活动代码：
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
switch (id){
case R.id.timer_menu:{
if(item.isChecked()) item.setChecked(false);
else item.setChecked(true);
}
case R.id.t1:{
if (item.isChecked()) item.setChecked(false);
else {
Intent i = new Intent(this,MyService.class);
stopService(i);
i.putExtra("chk", 't');
i.putExtra("t", 30000);
startService(i);
item.setChecked(true);
}
}
case R.id.t2:{
if(item.isChecked()) item.setChecked(false);
else {
Intent i = new Intent(this,MyService.class);
stopService(i);
i.putExtra("chk", 't');
i.putExtra("t", 60000);
startService(i);
item.setChecked(true);
}
}
case R.id.speechmenu:{
if(item.isChecked()) item.setChecked(false);
else {
Intent i = new Intent(this,MyService.class);
stopService(i);
i.putExtra("chk", 's');
startService(i);
item.setChecked(true);
}
}
}
return super.onOptionsItemSelected(item);
}
public void StartMethod(View v)
{
Intent i = new Intent(this,MyService.class);
i.putExtra("chk", 't');
i.putExtra("t", 30000);
startService(i);
}
public void EndMethod(View v)
{
Intent i = new Intent(this,MyService.class);
stopService(i);
}
}
这是我的服务：
