Question

我正在为学校制作应用程序..我的应用程序功能专门用于通过短信向用户发送最准确的位置。所以我使用融合位置api ...但现在我不知道如何将SMS管理器整合到我当前的应用程序中......目前我只构建了一个简单的应用程序，通过按下按钮显示用户的当前位置我只想获得有关如何在我的应用程序中合并SMS管理器的帮助。我还希望消息以URL形式加上坐标，以便接收者可以轻松跟踪用户。

这是我的代码主要活动

    import android.Manifest;
    import android.content.pm.PackageManager;
    import android.location.Location;
    import android.os.Looper;
    import android.support.annotation.NonNull;
    import android.support.v4.app.ActivityCompat;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.view.View;
    import android.widget.Button;
    import android.widget.TextView;

    import com.google.android.gms.location.FusedLocationProviderClient;
    import com.google.android.gms.location.LocationCallback;
    import com.google.android.gms.location.LocationRequest;
    import com.google.android.gms.location.LocationResult;
    import com.google.android.gms.location.LocationServices;

    public class MainActivity extends AppCompatActivity {
    private static final int REQUEST_CODE = 2300;
TextView textView;
Button sosbtn;
FusedLocationProviderClient fusedLocationProviderClient;
LocationRequest locationRequest;
LocationCallback locationCallback;

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case REQUEST_CODE: {
            if (grantResults.length > 0) {
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                } else if (grantResults[0] == PackageManager.PERMISSION_DENIED) {

                }


            }

        }

    }


}


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

    textView = (TextView) findViewById(R.id.textView);
    sosbtn = (Button) findViewById(R.id.sosbtn);

    if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.ACCESS_FINE_LOCATION)) {
        ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE);
    } else {
        buildLocationRequest();
        buildLocationCallBack();
        fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);

        sosbtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if (ActivityCompat.checkSelfPermission(MainActivity.this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                        && ActivityCompat.checkSelfPermission(MainActivity.this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE);
                    return;
                }
                fusedLocationProviderClient.requestLocationUpdates(locationRequest, locationCallback, Looper.myLooper());

            }
        });

    }

}

private void buildLocationCallBack() {
    locationCallback= new LocationCallback()
    {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            super.onLocationResult(locationResult);
            for(Location location:locationResult.getLocations())
                textView.setText(String.valueOf(location.getLatitude())+"/"+String.valueOf(location.getLongitude()));
        }
    };

}

private void buildLocationRequest() {
    locationRequest = new LocationRequest();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(5000);
    locationRequest.setFastestInterval(3000);
    locationRequest.setSmallestDisplacement(5);


}

}

非常感谢您的帮助。

Answer 1

以下是一个示例，将location对象声明为私有字段，然后单击按钮：

SmsManager smsManager = SmsManager.getDefault ();

String message = "My location: https://www.google.com/maps/@?api=1&map_action=map&center=" + location.getLatitude () + "," + location.getLongitude ();
String phoneNumber = "+1....";

smsManager.sendTextMessage (phoneNumber, null, message, null, null);

以上链接应将收件人重定向到Google地图。

SmsManager.sendTextMessage

不要忘记在清单中添加此权限：

<uses-permission android:name="android.permission.SEND_SMS"/>

和request the send sms permission在运行时。
