我在一个新项目中遵循Compass示例中使用的模式,并且大部分逻辑工作正常。但是,当我点击显示活卡时,会听到'咔嗒'声,但我的菜单活动不显示。我认为我错过了一个难题,但我还没有弄清楚到底是什么。如何让我的MenuActivity显示出来?
当我点击,除了点击,我也看到这一点的logcat:
01-08 10:02:26.796: I/ActivityManager(196): START {flg=0x10008000 cmp=com.example.speeddisplay/.SpeedDisplayMenuActivity} from pid -1
所以它看起来像它应该开始我的活动,但它并没有显示出来。以下是一些相关的代码......虽然我不确定问题出在哪里。在SpeedService.java
<service
android:name="com.example.speeddisplay.service.SpeedService"
android:enabled="true"
android:icon="@drawable/ic_drive_50"
android:label="@string/app_name" >
<intent-filter>
<action android:name="com.google.android.glass.action.VOICE_TRIGGER" />
</intent-filter>
<meta-data
android:name="com.google.android.glass.VoiceTrigger"
android:resource="@xml/voiceinput_speeddisplay" />
</service>
onStartCommand方法:在AndroidManifest.xml
服务部
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (Constants.DEBUG) {
Log.d(TAG, "onStartCommand");
}
if (liveCard == null) {
liveCard = timelineManager.createLiveCard(LIVE_CARD_ID);
speedRenderer = new SpeedRenderer(this, speedManager);
liveCard.setDirectRenderingEnabled(true);
liveCard.getSurfaceHolder().addCallback(speedRenderer);
// Display the options menu when the live card is tapped.
Intent menuIntent = new Intent(this, SpeedDisplayMenuActivity.class);
menuIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
liveCard.setAction(PendingIntent.getActivity(this, 0, menuIntent, 0));
liveCard.publish(PublishMode.REVEAL);
if(Constants.DEBUG){
Log.d(TAG, "liveCard published");
}
}
return START_STICKY;
}
这是我的SpeedDisplayMenuActivity.java。这些方法都没有被调用。
public class SpeedDisplayMenuActivity extends Activity {
private SpeedService.SpeedBinder speedService;
private boolean mResumed;
private ServiceConnection mConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
if (Constants.DEBUG) {
Log.e("Service Stuff", "Service connected.");
}
if (service instanceof SpeedService.SpeedBinder) {
speedService = (SpeedService.SpeedBinder) service;
openOptionsMenu();
}
if (Constants.DEBUG) {
Log.e("Service Stuff", "service was an instance of " + service.getClass().getName());
}
}
@Override
public void onServiceDisconnected(ComponentName name) {
// Do nothing.
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
if(Constants.DEBUG){
Log.e("Menu", "Created.");
}
super.onCreate(savedInstanceState);
bindService(new Intent(this, SpeedService.class), mConnection, 0);
}
@Override
protected void onResume() {
if(Constants.DEBUG){
Log.e("Menu", "Resumed.");
}
super.onResume();
mResumed = true;
openOptionsMenu();
}
@Override
protected void onPause() {
if(Constants.DEBUG){
Log.e("Menu", "Paused.");
}
super.onPause();
mResumed = false;
}
@Override
public void openOptionsMenu() {
if (Constants.DEBUG) {
Log.e("Options Menu", "Open");
}
if (mResumed && speedService != null) {
if (Constants.DEBUG) {
Log.e("Options Menu", "Open with correct params");
}
super.openOptionsMenu();
} else {
if (Constants.DEBUG) {
Log.e("Options Menu", "Open with INCORRECT params");
}
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
if (Constants.DEBUG) {
Log.e("Options Menu", "Created");
}
getMenuInflater().inflate(R.menu.speed, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (Constants.DEBUG) {
Log.e("Options Menu", "Item Selected");
}
switch (item.getItemId()) {
// case R.id.read_aloud:
// mCompassService.readHeadingAloud();
// return true;
case R.id.stop:
if (Constants.DEBUG) {
Log.e("Options Menu", "Stop");
}
stopService(new Intent(this, SpeedService.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
@Override
public void onOptionsMenuClosed(Menu menu) {
if (Constants.DEBUG) {
Log.e("Options Menu", "Closed");
}
super.onOptionsMenuClosed(menu);
unbindService(mConnection);
// We must call finish() from this method to ensure that the activity
// ends either when an
// item is selected from the menu or when the menu is dismissed by
// swiping down.
finish();
}
有人看到我失踪了吗?
您是否已在您的Manifest中注册了SpeedDisplayMenuActivity? – KickAss
我看不到SpeedDisplayMenuActivity.java它在您的清单文件中定义的任何地方。你检查了吗? –
你们都很棒。我总是忘记在我的Manifest中添加新的活动....我只是习惯于“正常”的Android应用程序崩溃,这就是我的记忆:)看起来玻璃器皿正好失败。 – Innova
