我是非常新的開發一個Android應用程序和編程在JAVA。我試圖開發這個應用程序，我的理解是，至少會顯示我的用戶界面，但我不斷得到一個faltal異常的問題：main？...你能幫我嗎？致命的例外︰主要在Android應用程序
這是XML的主要活動：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="@+id/Lights"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="@string/Lights"
android:textColor="@style/AppBaseTheme" />
<Button
android:id="@+id/SysOff"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/BluetoothConn"
android:layout_alignParentBottom="true"
android:layout_marginBottom="24dp"
android:text="@string/SysOff" />
<Button
android:id="@+id/SysOn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="@+id/SysOff"
android:layout_alignLeft="@+id/SysOff"
android:text="@string/SysOn" />
<Button
android:id="@+id/DoorsOpen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="@+id/DoorsClose"
android:layout_alignLeft="@+id/DoorsClose"
android:onClick="DoorsOpen"
android:text="@string/DoorsOpen" />
<Button
android:id="@+id/DoorsClose"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="@+id/SysOn"
android:layout_alignLeft="@+id/SysOn"
android:layout_marginBottom="21dp"
android:onClick="DoorsClose"
android:text="@string/DoorsClose" />
<Button
android:id="@+id/BluetoothConn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/Lights"
android:layout_below="@+id/Lights"
android:onClick="BTConnect"
android:text="@string/BluetoothConnect" />
<TextView
android:id="@+id/SysPwr"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/SysOn"
android:layout_alignLeft="@+id/DoorsClose"
android:text="@string/SysPwr" />
<Button
android:id="@+id/lightsOff"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/LightsOn"
android:layout_below="@+id/LightsOn"
android:onClick="LightsOff"
android:text="@string/LightsOff" />
<TextView
android:id="@+id/Doors"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/DoorsOpen"
android:layout_alignRight="@+id/Lights"
android:text="@string/Doors"
android:textAppearance="@style/AppBaseTheme" />
<Button
android:id="@+id/LightsOn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/BluetoothConn"
android:layout_below="@+id/BluetoothConn"
android:layout_marginTop="18dp"
android:onClick="LightsOn"
android:text="@string/LightsOn" />
</RelativeLayout>
這裏是MainActivity.java：
package com.example.mustangsound;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void BTConnect(){
}
public void LightsOn(){
}
public void LightsOff(){
}
public void DoorsOpen(){
}
public void DoorsClose(){
}
public void SysOn(){
}
public void SysOff(){
}
@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;
}
}
清單：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mustangsound"
android:versionCode="1"
android:versionName="1.0"
android:name="android.permission.BLUETOOTH">
<uses-sdk
android:minSdkVersion="17"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.mustangsound.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
而且logcat的：
