根据提供的引用内容,Android Studio本身并不能实现来电位置实时显示的功能。不过,你可以通过在应用中集成相关的API来实现该功能。具体来说,你可以使用Android TelephonyManager API来获取来电信息,使用Android Location API来获取设备位置信息,然后将这些信息结合起来在应用中实现来电位置实时显示的功能。
以下是一个简单的示例代码,演示如何使用TelephonyManager API获取来电信息和使用Location API获取设备位置信息:
```java
import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private TextView mLocationTextView;
private TelephonyManager mTelephonyManager;
private PhoneStateListener mPhoneStateListener;
private LocationManager mLocationManager;
private LocationListener mLocationListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLocationTextView = (TextView) findViewById(R.id.location_text_view);
// 获取TelephonyManager实例
mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
// 创建PhoneStateListener实例
mPhoneStateListener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
// 当来电状态为响铃或接听时,获取来电位置信息并显示在TextView中
if (state == TelephonyManager.CALL_STATE_RINGING || state == TelephonyManager.CALL_STATE_OFFHOOK) {
String location = getLocation();
mLocationTextView.setText(location);
}
}
};
// 注册PhoneStateListener
mTelephonyManager.listen(mPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
// 获取LocationManager实例
mLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// 创建LocationListener实例
mLocationListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
// 当设备位置发生变化时,更新TextView中的位置信息
String locationStr = "Latitude: " + location.getLatitude() + "\nLongitude: " + location.getLongitude();
mLocationTextView.setText(locationStr);
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
};
// 检查是否已经获取了定位权限
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// 如果没有定位权限,则请求权限
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 0);
} else {
// 如果已经获取了定位权限,则注册LocationListener
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mLocationListener);
}
}
@Override
protected void onDestroy() {
super.onDestroy();
// 取消注册PhoneStateListener和LocationListener
mTelephonyManager.listen(mPhoneStateListener, PhoneStateListener.LISTEN_NONE);
mLocationManager.removeUpdates(mLocationListener);
}
// 获取来电位置信息的方法
private String getLocation() {
String locationStr = "Unknown";
// 检查是否已经获取了定位权限
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// 如果没有定位权限,则返回Unknown
return locationStr;
}
// 获取最近一次的设备位置信息
Location location = mLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
// 如果获取到了设备位置信息,则返回位置信息字符串
locationStr = "Latitude: " + location.getLatitude() + "\nLongitude: " + location.getLongitude();
}
return locationStr;
}
}
```
请注意,上述代码仅仅是一个示例,实际上你需要根据具体的需求和场景来编写代码。
