Java 通过文本发送位置

我无法将我的位置坐标发送到手机

这里是Main.Java的代码

    package com.example.finder;

            sendSMS("09164232662", "wys" + " " + ALT + "   " + "spee" + " - "
                    + SPE);
        }


    });

}

private void sendSMS(String phoneNumber, String message) {
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage("09164232662", null, message, null, null);

这是清单文件的代码

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

</application>

问题是它正在接收信号，但却没有通过我的手机发送

让我知道我做错了什么

更改为：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    LocationListener ll = new mylocationlistener();
    lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, ll);
    final String ALT = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER).getLatitude();
    final String SPE = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER).getLongitude();

    Button btn1 = (Button) findViewById(R.id.checkin);


    btn1.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {

            sendSMS("09164232662", "wys" + " " + ALT + "   " + "spee" + " - "
                    + SPE);
        }


    });

    textLat = (TextView) findViewById(R.id.textLat);
    textLong = (TextView) findViewById(R.id.textLong);
    textAlt = (TextView) findViewById(R.id.textAlt);


}

我认为您的应用程序中存在概念问题。首先，您在清单中定义了两个入口点，它应该类似于：

<activity
        android:name=".Main"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
</activity>
<activity android:name="com.example.finder.GPS" />

然后你的CPS就没用了，你把它叫做什么

同样的活动叫什么

意向i=新意向（Main.this， 主要类别),； i、 putExtra（“wysokosc”，双倍toString（平台））； i、 putExtra（“速度”，双方向旋转（扑通声））； 星触觉（i）； 只需将pLong、pLat和pAlt定义为全局，并在onClick中使用它们来发送短信

希望这有帮助。

有日志吗？你得到的坐标完美吗？你添加了

SEND\u SMS

权限了吗？对不起，我是堆栈溢出新手，我对发布代码不太熟悉，所以我不得不一个接一个地做。尝试添加

Log.v（“Intent Extras”，ALT+SPE）紧接着
stringspe=extras.getString（“速度”）以确保您正确获取了额外的意图。
