的Android按鈕點擊應用崩潰

在主要活動即時在佈局的Android按鈕點擊應用崩潰

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 

    <fragment

     android:layout_height="match_parent"/> 

</RelativeLayout>

gotomap.java

public class gotomap extends Activity { 
    public gotomap(){} 
    getcoordinates loc; 
    double lati,longi; 
     private GoogleMap googleMap; 

     @TargetApi(Build.VERSION_CODES.HONEYCOMB) 
    @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      loc = new getcoordinates(this);    //getlocation 

      if(loc.canGetLocation())    
      {     
       lati = loc.getLatitude(); 
       longi = loc.getLongitude(); 
       Toast.makeText(this, "Your Location is - \nLat: " + lati + "\nLong: " + longi, Toast.LENGTH_LONG).show();  
      } 
      final LatLng locate = new LatLng(lati ,longi); 

      setContentView(R.layout.gotomap); 

      try { 
      if (googleMap == null) { 
       googleMap = ((MapFragment) getFragmentManager(). 
       findFragmentById(R.id.map)).getMap(); 
      } 

      catch (Exception e) { 
      e.printStackTrace(); 
      } 
     } 
    }

使用片段使用意圖作爲

btnlocate.setOnClickListener(new OnClickListener() 
    { 
     @Override 
     public void onClick(View v) { 
       Intent intent = new Intent(MainActivity.this, gotomap.class); 
       startActivity(intent); 
       MainActivity.this.finish(); 
     }   
    });

在gotomap.xml林

斷點甚而不去發送活動,,, 應用程序崩潰時調用的意圖...... 請做要緊......

後日志語句 –

添加到您的清單中刪除'公共gotomap（）{}''從類gotomap'。你不應該不必要地創建構造函數。 – SMR

崩潰與哪個異常？請將堆棧跟蹤添加到問題中。 – Timo

你必須在明顯的聲明你的活動，如：

<activity name="com.example.locato.gotomap"/>

首先，您需要確保清單文件中定義了「gotomap」活動。其次活動類的第一個字母應該是大寫字母。這是一般的Java標準。

<activity 
      android:name=".gotomap"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

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

確保每個活動應該提到在表現爲波紋管

<activity name="com.example.locato.gotomap"/> 

// use java naming conventions class name should be capital.

注意：要提高你的編碼標準使用Java命名約定一樣的類名應該開始資本

將AndroidManifest.xml中的gotomap.class條目作爲一個活動。

2016-02-02 05:22:01

<activity android:name=".gotomap" />

這裏面<application>標籤
