我正在Android Studio中制作Android游戏。
我首先编写了游戏循环代码。然后我创建了一个欢迎页面/开始页面并将其添加到onclick事件中。
但是当我运行应用程序并单击“开始”按钮时,应用程序会突然停止。这是Java,XML和清单文件。我错过了什么吗?
我的主要活动(Game.java):
public class Game extends ActionBarActivity{
private static Button button_sbm;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//turn off title
requestWindowFeature(Window.FEATURE_NO_TITLE);
//set to full screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_game);
onClickButtonListener();
}
public void onClickButtonListener(){
button_sbm=(Button)findViewById(R.id.button);
button_sbm.setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent=new Intent("com.project.androidgame.GAME");
startActivity(intent);
}
}
);
}
/*public void startGame(){
Intent intent=new Intent(Splash.this, Game.class);
startActivity(intent);
}*/
activity_game.xml
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="START"
android:textSize="50sp"
android:id="@+id/button"
android:layout_centerVertical="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="How to play"
android:textSize="24sp"
android:id="@+id/button2"
android:layout_below="@+id/button"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
起始页面的活动(Splash.java):
public class Splash extends Activity {
MediaPlayer ourSong;
@Override
protected void onCreate(Bundle ILoveFootball) {
super.onCreate(ILoveFootball);
setContentView(R.layout.splash);
ourSong=MediaPlayer.create(Splash.this,R.raw.splashsound);
ourSong.start();
Thread timer=new Thread(){
public void run()
{
try{
sleep(5000);
}catch(InterruptedException e){
e.printStackTrace();
}finally{
Intent openStartingPoint=new Intent("com.project.androidgame.GAME");
startActivity(openStartingPoint);
}
}
};
timer.start();
}
@Override
protected void onPause() {
super.onPause();
ourSong.release();
finish();
}
}
splash.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/splash_back">
清单
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:screenOrientation="landscape"
android:name=".Splash" android:label="AndroidGame">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:screenOrientation="landscape"
android:name=".Game" android:label="AndroidGame">
<intent-filter>
<action android:name="com.project.androidgame.GAME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
答案 0 :(得分:1)
按照此步骤编辑代码
在清单中,删除第二个活动中的intent-filter,intent-filter仅用于识别启动活动。改变这个
<activity android:screenOrientation="landscape"
android:name=".Game" android:label="AndroidGame">
<intent-filter>
<action android:name="com.project.androidgame.GAME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
到此
<activity android:screenOrientation="landscape"
android:name=".Game" android:label="AndroidGame">
</activity>
启动活动的最佳方式是当前内容到下一个班级一个例子
Intent intent=new Intent(Splash.this, Game.class);
startActivity(intent);
