我正在开发Android Wear OS 2.0应用程序。每当用户从给定号码获得SMS时,手表应该开始振动,并且应该出现具有给定文本的UI,其具有停止振动的按钮。它的工作方式如下:
在SmsReciever.java
我正在检查电话号码是否匹配,或者UI屏幕是否已激活。
public class SmsReceiver extends BroadcastReceiver {
//interface
private static SmsListener mListener;
@Override
public void onReceive(Context context, Intent intent) {
Bundle data = intent.getExtras();
Object[] pdus = (Object[]) data.get("pdus");
for(int i=0;i<pdus.length;i++){
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i], "3gpp");
String sender = smsMessage.getDisplayOriginatingAddress();
String alertPhoneNumber = "301112233";
if (sender.toLowerCase().contains(alertPhoneNumber.toLowerCase()))
{
String messageBody = smsMessage.getMessageBody();
//Pass the message text to interface
mListener.messageReceived(messageBody);
} else if (AlarmActivity.active) {
Intent intent1 = new Intent();
intent1.setClassName("hu.asd.watchtest", "hu.asd.watchtest.AlarmActivity");
intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent1);
}
}
}
public static void bindListener(SmsListener listener) {
mListener = listener;
}
}
我需要其他部分,因为有时当用户界面处于活动状态时,我已收到新消息,振动停止了。因此该部分启动AlarmActivity
(处理振动)。
在MainActivity.java
我绑定一个新的侦听器,所以现在每次我在SmsReciever
中收到正确的消息时,AlarmActivity
都应该运行:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
requestPermissions(Manifest.permission.RECEIVE_SMS, PERMISSIONS_REQUEST_RECEIVE_SMS);
SmsReceiver.bindListener(new SmsListener() {
@Override
public void messageReceived(String messageText) {
Intent myIntent = new Intent(MainActivity.this, AlarmActivity.class);
MainActivity.this.startActivity(myIntent);
}
});
}
在AlarmActivity.java
应用程序唤醒屏幕,然后获取Vibrator
,将onClickListeners设置为停止振动按钮,然后启动实际振动。我也在这里更改了活动状态:
public class AlarmActivity extends WearableActivity {
static boolean active = false;
@Override
public void onResume() {
super.onResume();
active = true;
}
@Override
public void onStart() {
super.onStart();
active = true;
}
@Override
public void onStop() {
super.onStop();
active = false;
}
@Override
public void onPause() {
super.onPause();
active = false;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_alarm);
PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
final PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP|PowerManager.SCREEN_BRIGHT_WAKE_LOCK,
"MyWakelockTag");
wakeLock.acquire();
findViewById(R.id.stop_button).getBackground().setLevel(5000);
final Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
final long[] mVibratePattern = new long[]{0, 400, 800, 600, 800, 800, 800, 1000};
final int[] mAmplitudes = new int[]{0, 255, 0, 255, 0, 255, 0, 255};
final Button stopButton = findViewById(R.id.stop_button);
stopButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
vibrator.cancel();
wakeLock.release();
new SendEmail().execute();
Intent myIntent = new Intent(AlarmActivity.this, MainActivity.class);
AlarmActivity.this.startActivity(myIntent);
}
});
setAmbientEnabled();
vibrator.vibrate(VibrationEffect.createWaveform(mVibratePattern, mAmplitudes, 0)); // 0 to repeat endlessly.
}
}
如果用户按下按钮,则MainActivity将再次启动。问题是,在50个案例中,我可以发送多条短信,手表会振动,直到我按下停止按钮,但在1个案例中,它只会振动一次,然后它会停止振动。如果AlarmActivity
已经激活并振动,或者之前已取消振动,通常会发生这种情况。我猜测我在使用意图或与Vibrator实例有关的东西上做了很多工作?或者当我得到一个新文本时,手表需要振动器,我的应用程序无法获得它?
这是我的第一个Android应用程序,我尝试了很多不同的实现,但仍然不完美。
