                    //要求用户在设置中启用GPS /网络
                    gps.showSettingsAlert();
                }            }
        });
    }}


解决方案

喜使用以下code:

步骤1创建以下类LatLong.java:

 公共类的LatLong {    //私有变量
    INT _id;
    串_lat;
    串_long;
    //空的构造
    公众的LatLong(){    }
    //构造
    公众的LatLong(INT ID,字符串纬度,经度字符串){
        this._id = ID;
        this._lat =纬度;
        this._long =经度;
    }    //构造
    公众的LatLong(字符串纬度,经度字符串){
        this._lat =纬度;
        this._long =经度;
    }
    //获取ID
    公众诠释的getID(){
        返回this._id;
    }    //设置ID
    公共无效SETID(INT ID){
        this._id = ID;
    }    公共字符串get_lat(){
        返回_lat;
    }
    公共无效set_lat(字符串_lat){
        this._lat = _lat;
    }
    公共字符串get_long(){
        返回_long;
    }
    公共无效set_long(字符串_long){
        this._long = _long;
    }}

第2步:创建以下DB类:DatabaseHandler.java

 进口android.content.ContentValues​​;
进口android.content.Context;
进口android.database.sqlite.SQLiteDatabase;
进口android.database.sqlite.SQLiteOpenHelper;公共类数据库处理器扩展SQLiteOpenHelper {    //所有静态变量
    //数据库版本
    私有静态最终诠释DATABASE_VERSION = 1;    //数据库名称
    私有静态最后弦乐DATABASE_NAME =GPS;    //联系人表名
    私有静态最后弦乐TABLE_CONTACTS =gracking;    //联系方式表列名
    私有静态最后弦乐KEY_ID =ID;
    私有静态最后弦乐KEY_LAT =纬度;
    私有静态最后弦乐KEY_LONG =长;    公共数据库处理器(上下文的背景下){
        超(背景下,DATABASE_NAME,空,DATABASE_VERSION);
    }    //创建表
    @覆盖
    公共无效的onCreate(SQLiteDatabase DB){
        字符串CREATE_CONTACTS_TABLE =CREATE TABLE+ TABLE_CONTACTS +(
                + KEY_ID +INTEGER PRIMARY KEY,+ KEY_LAT +TEXT
                + KEY_LONG +TEXT+);
        db.execSQL(CREATE_CONTACTS_TABLE);
    }    //数据库升级
    @覆盖
    公共无效onUpgrade(SQLiteDatabase分贝,INT oldVersion,诠释静态网页){
        如果存在//删除旧的表
        db.execSQL(DROP TABLE IF EXISTS+ TABLE_CONTACTS);        //再次创建表
        的onCreate(DB);
    }    / **
     *所有CRUD(创建,读取,更新,删除)操作
     * /    //添加新值
    无效addvalues​​(价值的LatLong){
        SQLiteDatabase分贝= this.getWritableDatabase();        ContentValues​​值=新ContentValues​​();
        values​​.put(KEY_LAT,value.get_lat()); // 联系人姓名
        values​​.put(KEY_LONG,value.get_long()); // 联系电话        //插入行
        db.insert(TABLE_CONTACTS,空,价值);
        db.close(); //关闭数据库连接
    }
}

第三步:添加以下code在你的类:

  btnShowLocation.setOnClickListener(新View.OnClickListener(){            @覆盖
            公共无效的onClick(查看为arg0){
                //创建类对象
                GPS =新GPSTracker(AndroidGPSTrackingActivity.this);                //检查是否启用GPS
                如果(gps.canGetLocation()){                    双纬度= gps.getLatitude();
                    双经度= gps.getLongitude();
  数据库处理器DB =新的数据库处理器(本);        / **
         * CRUD操作
         * * /
        //插入latlongs
        Log.d(插入,插入..);
        db.addvalues​​(新的LatLong(latvalue,的longValue));                    Toast.makeText(getApplicationContext(),您现在的位置是 - \\ nLat:+纬度+\\ nLong:+经度,Toast.LENGTH_LONG).show();
                }其他{
                    //无法获取位置
                    未启用// GPS或网络
                    //要求用户在设置中启用GPS /网络
                    gps.showSettingsAlert();
                }            }
        });

enter image description hereI am making a simple android app to get the location of an android user and I need to send the latitude and longitude to the MySQL database. How can I do that with this kind of code segment?

DatabaseHandler class

package com.example.gpstracking;

import android.content.ContentValues;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;



public class DatabaseHandler extends SQLiteOpenHelper {

    // All Static variables
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "gps";

    // Contacts table name
    private static final String TABLE_CONTACTS = "location";

    // Contacts Table Columns names
    private static final String KEY_ID = "id";
    private static final String KEY_LAT = "lat";
    private static final String KEY_LONG = "long";

     public DatabaseHandler(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Creating Tables
    @Override
    public void onCreate(SQLiteDatabase db) {
        String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_CONTACTS + "("
                + KEY_ID + " INTEGER PRIMARY KEY," + KEY_LAT + " TEXT,"
                + KEY_LONG + " TEXT" + ")";
        db.execSQL(CREATE_CONTACTS_TABLE);
    }

    // Upgrading database
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // Drop older table if existed
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_CONTACTS);

        // Create tables again
        onCreate(db);
    }

    /**
     * All CRUD(Create, Read, Update, Delete) Operations
     */

    // Adding new values
    void addvalues(LatLong value) {
        SQLiteDatabase db = this.getWritableDatabase();

        ContentValues values = new ContentValues();
        values.put(KEY_LAT, value.get_lat()); // Contact Name
        values.put(KEY_LONG,  value.get_long()); // Contact Phone

        // Inserting Row
        db.insert(TABLE_CONTACTS, null, values);
        db.close(); // Closing database connection
    }


}

Here is my Android Activity

package com.example.gpstracking;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class AndroidGPSTrackingActivity extends Activity {

    Button btnShowLocation;

    // GPSTracker class
    GPSTracker gps;

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

        btnShowLocation = (Button) findViewById(R.id.btnShowLocation);

        // show location button click event
        btnShowLocation.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // create class object
                gps = new GPSTracker(AndroidGPSTrackingActivity.this);

                // check if GPS enabled

解决方案

hi use the following code:

Step 1 Create the following class LatLong.java:

public class LatLong {

    //private variables
    int _id;
    String _lat;
    String _long;


    // Empty constructor
    public LatLong(){

    }
    // constructor
    public LatLong(int id, String latitude, String longitude){
        this._id = id;
        this._lat = latitude;
        this._long = longitude;
    }

    // constructor
    public LatLong(String latitude, String longitude){
        this._lat = latitude;
        this._long = longitude;
    }
    // getting ID
    public int getID(){
        return this._id;
    }

    // setting id
    public void setID(int id){
        this._id = id;
    }

    public String get_lat() {
        return _lat;
    }
    public void set_lat(String _lat) {
        this._lat = _lat;
    }
    public String get_long() {
        return _long;
    }
    public void set_long(String _long) {
        this._long = _long;
    }

}

Step 2:Create the following db class:DatabaseHandler.java

import android.content.ContentValues;
import android.content.Context;


import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DatabaseHandler extends SQLiteOpenHelper {

    // All Static variables
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "gps";

    // Contacts table name
    private static final String TABLE_CONTACTS = "gracking";

    // Contacts Table Columns names
    private static final String KEY_ID = "id";
    private static final String KEY_LAT = "lat";
    private static final String KEY_LONG = "long";

    public DatabaseHandler(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Creating Tables
    @Override
    public void onCreate(SQLiteDatabase db) {
        String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_CONTACTS + "("
                + KEY_ID + " INTEGER PRIMARY KEY," + KEY_LAT + " TEXT,"
                + KEY_LONG + " TEXT" + ")";
        db.execSQL(CREATE_CONTACTS_TABLE);
    }

    // Upgrading database
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // Drop older table if existed
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_CONTACTS);

        // Create tables again
        onCreate(db);
    }

    /**
     * All CRUD(Create, Read, Update, Delete) Operations
     */

    // Adding new values
    void addvalues(LatLong value) {
        SQLiteDatabase db = this.getWritableDatabase();

        ContentValues values = new ContentValues();
        values.put(KEY_LAT, value.get_lat()); // Contact Name
        values.put(KEY_LONG,  value.get_long()); // Contact Phone

        // Inserting Row
        db.insert(TABLE_CONTACTS, null, values);
        db.close(); // Closing database connection
    }


}

Step 3:Add the following code in your class:

 btnShowLocation.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // create class object
                gps = new GPSTracker(AndroidGPSTrackingActivity.this);

                // check if GPS enabled
                if(gps.canGetLocation()){

                    double latitude = gps.getLatitude();
                    double longitude = gps.getLongitude();


  DatabaseHandler db = new DatabaseHandler(this);

        /**
         * CRUD Operations
         * */
        // Inserting latlongs
        Log.d("Insert: ", "Inserting ..");
        db.addvalues(new LatLong("latvalue", "longvalue"));

                    Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show();
                }else{
                    // can't get location
                    // GPS or Network is not enabled
                    // Ask user to enable GPS/network in settings
                    gps.showSettingsAlert();
                }

            }
        });
