此示例演示了如何在 Android 上以编程方式获取当前 GPS 位置。
步骤 1 − 在 Android Studio 中创建一个新项目，前往"文件"->"新建项目"，并填写所有必需信息以创建新项目。
步骤 2 − 将以下代码添加到 res/layout/activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_margin="16dp" android:gravity="center_horizontal" android:orientation="vertical"> <TextView android:id="@+id/location" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Current GPS Loaction" android:textSize="24sp" android:textStyle="bold" /> <Button android:id="@+id/getLocation" android:text="Get location" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>
步骤 3 − 将以下代码添加到 src/MainActivity.java
import android.content.pm.PackageManager;
import android.location.Location;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
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.LocationServices;
import com.google.android.gms.tasks.OnSuccessListener;
import static android.Manifest.permission.ACCESS_FINE_LOCATION;
public class MainActivity extends AppCompatActivity {
private FusedLocationProviderClient client;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
requestPermission();
client = LocationServices.getFusedLocationProviderClient(this);
Button button = findViewById(R.id.getLocation);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (ActivityCompat.checkSelfPermission(MainActivity.this, ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED ) {
return;
}
client.getLastLocation().addOnSuccessListener(MainActivity.this, new OnSuccessListener() {
@Override
public void onSuccess(Location location) {
if (location != null) {
TextView textView = findViewById(R.id.location);
textView.setText(location.toString());
}
}
});
}
});
}
private void requestPermission(){
ActivityCompat.requestPermissions(this, new String[]{ACCESS_FINE_LOCATION}, 1);
}
}
步骤 4 − 将以下代码添加到 androidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.sample"> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>
让我们尝试运行您的应用程序。假设您已将实际的 Android 移动设备连接到电脑。要从 Android Studio 运行该应用程序，请打开项目的某个 Activity 文件，然后点击工具栏上的"运行"
图标。选择您的移动设备作为选项，然后检查您的移动设备是否显示您的默认屏幕 −
