我的Android应用程序突然停止工作
问题描述:
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"?>

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Javasource
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>
