我的Android应用程序突然停止工作

-5

我被这个问题困扰了，我得快速解决这个问题。请帮帮我。所以目前我每次粘贴一些我在网上找到的新代码时都会遇到崩溃。 [附注： IM在android系统编程对于新手]我的Android应用程序突然停止工作

这是我AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="birada1.tulungatung.ph.myapplication2"> 

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/chess_icon" 
    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>

我做了一些小的改动MainActivity.java

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 

public class MainActivity extends Activity implements View.OnClickListener { 

private Button btn; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    Button one = (Button) findViewById(R.id.button2); 
    Button two = (Button) findViewById(R.id.button3); 
    Button three = (Button) findViewById(R.id.button4); 

    one.setOnClickListener(this); 
    two.setOnClickListener(this); 
    three.setOnClickListener(this); 
} 


@Override 
public void onClick(View view) { 
    switch (view.getId()) { 

     case R.id.button2: 
      Intent intenthistory = new Intent(this, ChessHistoryActivity.class); 
      startActivity(intenthistory); 
      // do your code 
      break; 

     case R.id.button3: 
      Intent intenthistory2 = new Intent(this, LearnChessActivity.class); 
      startActivity(intenthistory2); 
      break; 
     case R.id.button4: 
      Intent intenthistory3 = new Intent(this, GrandmastersActivity.class); 
      startActivity(intenthistory3); 
      break; 


     default: 
    } 

} 
}

activity_main.xml中

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

检查红色日志和张贴在这里。 – TruongHieu

将您的活动添加到您的清单..由于意图活动导致其崩溃尚未注册 – ZeroOne

你有没有宣布ChessHistoryActivity/LearnChessActivity/GrandmastersA AndroidManifest.xml中的活动？如果不加

<activity android:name=".ChessHistoryActivity" 
      android:launchMode="singleTask" /> 

<activity android:name=".LearnChessActivity" 
      android:launchMode="singleTask" /> 

<activity android:name=".GrandmastersActivity" 
      android:launchMode="singleTask" />

从清单中删除你的应用程序标签，并粘贴此应用标签和尝试，您的问题将得到解决。

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/chess_icon" 
    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> 
    <activity android:name=".ChessHistoryActivity"/> 
    <activity android:name=".LearnChessActivity"/> 
    <activity android:name=".GrandmastersActivity"/> 
</application>

首先添加ChessHistoryActivity.java，LearnChessActivity.java和GrandmastersActivity.java类到您的Java source文件夹(If not added yet)。

文件夹：./app/src/main/java/birada1.tulungatung.ph.myapplication2/

声明ChessHistoryActivity，LearnChessActivity和GrandmastersActivity在AndroidManifest.xml文件。

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="birada1.tulungatung.ph.myapplication2"> 

    <application 
     android:allowBackup="true" 
     android:icon="@mipmap/chess_icon" 
     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> 

     <activity android:name=".ChessHistoryActivity" /> 
     <activity android:name=".LearnChessActivity" /> 
     <activity android:name=".GrandmastersActivity" /> 

    </application> 
</manifest>

希望这将有助于〜
