Android Location LocationListener 总是调用 onProviderDisabled

Question

我的设备：Android 6.0.1，这是我的应用程序设置。

compileSdkVersion 24
buildToolsVersion "24.0.1"

minSdkVersion 21
targetSdkVersion 24

LocationListener onLocationChanged() 永远不会被调用。它总是调用onProviderDisabled()。

这里是MainActivity.java

TextView mTextView;
LocationManager mLocationManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mTextView = (TextView) findViewById(R.id.tv);

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return;
    }

    mLocationManager = (LocationManager) this
            .getSystemService(Context.LOCATION_SERVICE);
    mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1 * 1000, 0.00001F,
            locationListener);
}

private void updateUIToNewLocation(Location location) {
    Log.d("hello","updateUIToNewLocation = ");
    if (location != null) {
        mTextView.setText("Latitude：" + location.getLatitude() + "\nLongitude:"
                + location.getLongitude());
    } else {
        mTextView.setText("error");
    }
}

LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
        Log.d("hello","onLocationChanged");
        System.out.println("onLocationChanged");
        System.out.println("Latitude：" + location.getLatitude() + "\nLongitude"
                + location.getLongitude());
        updateUIToNewLocation(location);
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {
        Log.d("hello","onStatusChanged");
        System.out.println("onStatusChanged");
        System.out.println("privider:" + provider);
        System.out.println("status:" + status);
        System.out.println("extras:" + extras);
    }

    public void onProviderEnabled(String provider) {
        Log.d("hello","onProviderEnabled");
        System.out.println("onProviderEnabled");
        System.out.println("privider:" + provider);
    }

    public void onProviderDisabled(String provider) {
        Log.d("hello","onProviderDisabled");
        System.out.println("onProviderDisabled");
        System.out.println("privider:" + provider);
    }
};

这是清单 xml 中的权限和 Activity 标签。

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<!-- Needed only if your app targets Android 5.0 (API level 21) or higher. -->
<uses-feature android:name="android.hardware.location.network"/>
<uses-feature android:name="android.hardware.location.gps" />

<uses-sdk
    android:minSdkVersion="23"
    android:targetSdkVersion="24"/>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
</application>

这个应用程序可以在Android 5.1 上直接运行，但在Android 6.0.1 上无法运行。希望有人可以帮助我。我不明白这个问题。

我也面临同样的问题，在我的案例解决方案中，我发现在移动中转到 设置->位置->位置模式->更改为适当的模式（在您使用的提供商之外）。 希望也适用于您的情况。
