我正在编写一个包含有关入口信息的应用程序。这是我的第一个应用程序，所以我对 android 有点陌生。

我有一个由 8 个按钮组成的菜单。对于其中一个，它会打开一个具有两个图像按钮的活动。每个图像按钮都会打开一个不同的活动，其中只有一个文本视图。

我的问题是这个。当我第一次运行应用程序时，如果我点击任何一个图像按钮，它就会崩溃。然后返回菜单。如果我回到任一图像按钮，现在它可以工作了。

我在运行 4.2.2 调试的 GS4 上运行我的应用程序，它给了我找不到错误源。不知道出了什么问题。

有两个按钮的类

public class Factions extends Activity implements View.OnClickListener {
ImageButton resis, enligh;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_factions);
    setup();
}

private void setup() {
    resis = (ImageButton) findViewById(R.id.ibResistance);
    resis.setOnClickListener(this);

    enligh = (ImageButton) findViewById(R.id.ibEnlightened);
    enligh.setOnClickListener(this);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.factions, menu);
    return true;
}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    Intent i;
    switch (v.getId()) {
    case R.id.ibEnlightened:
        i = new Intent(getApplicationContext(), AboutEnlightened.class);
        startActivity(i);
        break;

    case R.id.ibResistance:
        i = new Intent(getApplicationContext(), AboutResistance.class);
        startActivity(i);
        break;
    }
}

}

该类的 xml 

<ImageButton
    android:id="@+id/ibResistance"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight="1"
    android:src="@drawable/resistance_logo_button" />

<ImageButton
    android:id="@+id/ibEnlightened"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight="1"
    android:src="@drawable/enlightened_logo_button" />

两个文本视图的类只有 onCreate 和 onCreateOptionsMenu 方法。我不需要更改它们或添加任何东西。如果您需要任何其他信息，请告诉我。提前致谢。

这是您应该感兴趣的行：

Caused by: java.lang.OutOfMemoryError 08-09 22:07:00.571: E/AndroidRuntime(11028):     at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)

你用的是安卓虚拟设备吗？尝试在虚拟设备管理器中增加 VM。
