Android判断用户是否可以获取定位信息

1.是否注册权限

<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_WIFI_STATE" />  
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />  
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />  
<uses-permission android:name="android.permission.INTERNET" />  

2./判断是否获得定位权限

//判断是否获得定位权限
    private boolean checkPermissionGranted(String permission) {
        return PermissionChecker.checkPermission(this, permission, android.os.Process.myPid(), android.os.Process.myUid(), getPackageName()) == PackageManager.PERMISSION_GRANTED;
    }
    boolean isLocation1 = checkPermissionGranted(Manifest.permission.ACCESS_FINE_LOCATION);
        boolean isLocation2 = checkPermissionGranted(Manifest.permission.ACCESS_COARSE_LOCATION);
```if(isLocation1 && isLocation2) {
            //获取成功的操作
            ...
        }else{
            Toast.makeText(MainActivity.this,"获取位置失败，未开启定位权限!", Toast.LENGTH_SHORT).show();
        }

3.是否开启定位服务

  /**
 * 判断GPS是否开启，GPS或者AGPS开启一个就认为是开启的
 * @param context
 * @return true 表示开启
 */
  public static final boolean isOPenGPS(final Context context) {
    LocationManager locationManager
            = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    // GPS定位
    boolean gps = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
    // 网络服务定位
    boolean network = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    if (gps || network) {
        return true;
    } return false;
}
