誰能告訴我個XML對這一計劃

Question

（ANDROID GPS） 其實我在Android的新的，因爲我是一個C++程序員，所以現在面臨這個計劃的一些困難是拿Android手機的gpslocation和將其作爲sms發送給給定的號碼。但由於它是在Java中，請能有人告訴我不同​​的XML對這一計劃將是...我的意思的字符串，主要個XML

package com.adzz.gps; 

import android.os.Bundle; 
import android.app.Activity; 
import android.view.Menu; 
import android.location.Location; 
import android.location.LocationListener; 
import android.location.LocationManager; 
import android.content.Context; 
import android.telephony.SmsManager; 
import android.view.Gravity; 
import android.view.View; 
import android.widget.Button; 
import android.widget.TextView; 
import android.widget.Toast; 
import android.view.View.OnClickListener;  


public class MainActivity extends Activity { 
    String m; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.main); 
LocationManager manager= (LocationManager) 
this.getSystemService(Context.LOCATION_SERVICE); 
LocationListener listener =new LocationListener() { 
@Override 

public void onStatusChanged(String provider, int status, Bundle extras) { 
// TODO Auto-generated method stub 

} 

@Override 
public void onProviderEnabled(String provider) { 
// TODO Auto-generated method stub 

} 

@Override 
public void onProviderDisabled(String provider) { 
} 
@Override 
public void onLocationChanged(Location location) { 
final String phoneNumber="9453603045"; 

double lat1=location.getLatitude(); 
Double d1= new Double(lat1); 
double longi1=location.getLongitude(); 
Double d2=new Double(longi1); 
m="latitude = "+ d1.toString() + "and latitude = "+ d2.toString(); 
SmsManager smsManager = SmsManager.getDefault(); 
smsManager.sendTextMessage(phoneNumber, null, m, null, null); 
TextView lat= (TextView) findViewById(R.id.lat); 
TextView longi=(TextView) findViewById(R.id.longi); 

lat.setText("latitude = "+lat1); 
longi.setText("longitude ="+longi1); 
} 
}; 
manager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 25, 
listener); 
Button b= (Button) findViewById(R.id.button1); 
b.setOnClickListener(new OnClickListener() { 

@Override 
public void onClick(View v) { 

Toast toast=Toast.makeText(Main.this, m, 5000); 
toast.setGravity(Gravity.CENTER, 0, 0); 
toast.show(); 
} 
}); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
// Inflate the menu; this adds items to the action bar if it is present. 
getMenuInflater().inflate(R.menu.main, menu); 
return true; 
} 

}

<?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:orientation="vertical" > 

     <TextView 
      android:id="@+id/lat" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginTop="10dp" /> 

     <TextView 
      android:id="@+id/longi" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginTop="10dp" /> 

     <Button 
      android:id="@id/button1" 
      android:layout_gravity="center" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" /> 

    </LinearLayout> 

Answer 2

首先，你需要創建佈局文件夾中的main.xml res目錄。這是在你的Activity中加載的主要佈局，在main.xml中取兩個TextView，id爲lat和longi。 main.xml如下所示。

<?xml version="1.0" encoding="utf-8"?> 

<TextView 
    android:id="@+id/lat" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentTop="true" 
    android:layout_centerHorizontal="true" 
    android:layout_marginTop="195dp" 
    android:text="Lattitude" /> 

<TextView 
    android:id="@+id/longi" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignLeft="@+id/textView2" 
    android:layout_alignParentTop="true" 
    android:layout_marginTop="82dp" 
    android:text="Longitude" />
