Question

我在eclipse中的程序遇到了一个奇怪的问题。我有多个活动，我的意图方法跳转到另一个活动。它正在致力于其他活动，但对于某项活动，它不起作用，因此，应用程序崩溃。我有以下活动意图跳：

GameMenu意图按钮指向＆gt; AppInfo＆amp; InstructionScreen （工作正常）
AppInfo意图按钮指示返回＆gt; GameMenu（工作正常）
Instruction意图按钮指向＆gt; ColorGame活动（崩溃）。

以下是InstructionScreen的代码：

public class InstructionScreen extends Activity {
ViewFlipper c2s;
ImageView c2s1,c2s2;
MediaPlayer buttonClick;
Intent playGame;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_instruction_screen);
    c2s = (ViewFlipper) findViewById (R.id.click2start);
    buttonClick = MediaPlayer.create(this, R.raw.buttonclick);
    c2s.setFlipInterval(100);
    c2s.startFlipping();
    this.clickToStart();
}

private void clickToStart() {
    c2s1 = (ImageView) findViewById (R.id.c2s1);
    c2s2 = (ImageView) findViewById (R.id.c2s2);
    c2s1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            buttonClick.start();
            c2s.stopFlipping();
            playGame = new Intent(InstructionScreen.this, ColorGame.class);
            playGame.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(playGame);

        }
    });

    c2s2.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            buttonClick.start();
            c2s.stopFlipping();
            playGame = new Intent(InstructionScreen.this, ColorGame.class);
            playGame.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(playGame);

        }
    });

}


}

以下是ColorGame的代码:(内容未完成，但我怀疑是问题）

public class ColorGame extends Activity {
TextView timer, score;
ViewFlipper colors;
ImageView yellow, red, green;
MediaPlayer backgroundMusic;
int gameTime, points;
Random colorNum;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_color_game);
    backgroundMusic = MediaPlayer.create(this, R.raw.colorgamebgs);
    backgroundMusic.start();

    yellow = (ImageView) findViewById(R.id.yellowbar);
    red = (ImageView) findViewById(R.id.redbar);
    green = (ImageView) findViewById(R.id.greenbar);

    colorNum = new Random();

    timer = (TextView) findViewById(R.id.timer);
    timer.setText("START");

    this.startGame();
}


private void startGame() {
    // TODO Auto-generated method stub

}


 }

此外，还有XML for ColorGame：

Answer 1

根据Logcat

"Caused by: android.view.InflateException: Binary XML file line #42: Error inflating class <unknown>
05-03 20:46:19.634: E/AndroidRuntime(28535):    at android.view.LayoutInflater.createView(LayoutInflater.java:619)"

第42行出错。请检查您的XML

Answer 2

你有OutOfMemoryError

Caused by: java.lang.OutOfMemoryError  
at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)

看起来您正在尝试加载大型位图或其他类似内容，请在layout处查看第{42行ColorGame Activity

Unable to start activity ComponentInfo  
{com.ics136.colorgame/com.ics136.colorgame.ColorGame}:   
android.view.InflateException: Binary XML file line #42: Error inflating class <unknown>

Answer 3

你有一些例外，比如

Caused by: android.view.InflateException: Binary XML file line #42
Caused by: android.view.InflateException: Binary XML file line #42: Error inflating class <unknown>
Caused by: java.lang.reflect.InvocationTargetException
Caused by: java.lang.OutOfMemoryError

正如@JafarKhQ所说，可能你的图片太大而且正在消耗应用程序的内存预算，请检查ColorGame中的图片是否过大。

修改

我敢打赌问题是你RelativeLayout的背景图片，正如你在评论中所说，图像差不多是2Mb，我认为问题就在那里。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"       xmlns:tools="http://schemas.android.com/tools"
    <!-- .... -->
    android:background="@drawable/colorgame"
    <!-- .... -->
>

尝试缩小图像的大小或将其删除以查找是否存在问题。

OnClickListener下的Intent方法
