Question

编辑：

似乎我的按钮样式导致了问题。

编辑代码

buttonL.setOnTouchListener(new View.OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction()==MotionEvent.ACTION_DOWN)
                buttonL.setBackgroundResource(R.drawable.lights_over);
            if(event.getAction()==MotionEvent.ACTION_UP || event.getAction()==MotionEvent.ACTION_CANCEL)
                buttonL.setBackgroundResource(R.drawable.lights);
            return false;
        }
    });

上面的代码适用于4.2及以上的原因。

将它放在未来的人们身上。

当我尝试将setContentView()方法调用到布局时，我的应用程序崩溃了。

我尝试了一些解决方案，当我删除按钮的样式时，错误就消失了。

似乎我用于按钮的样式导致了这种情况。

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable/lights_over" />
<item android:state_focused="true" android:drawable="@drawable/lights_over" />
<item android:state_selected = "true" android:drawable = "@drawable/lights_over" />
<item android:drawable = "@drawable/lights" android:id="@+id/button_L"/>
</selector>

Answer 1

从logcat开始，问题就是Button的背景。我认为这是一个很大的形象，所以它会溢出你的记忆。

<强>第一
尝试删除menu_system.xml中的任何@drawable，特别是按钮
中的android：background 运行你的工作，然后知道在哪里看。

第二（解决方法）
将背景图像文件移动到更大的文件夹
从drawable到drawable-xhdpi

Answer 2

试试这个：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    Thread splash=new Thread(){
        public void run(){
            try{
                sleep(2000);
            }catch(Exception e){
                e.printStackTrace();
            }finally{
                startActivity(new Intent(getApplicationContext(),StartMenu.class));
                finish();
            }
        }
    };

    splash.start();
}

你的Manifest.xml：

 <activity
 android:name="com.example.mapcard.Splash"
 android:label="@string/app_name" >
 <intent-filter>
 <action android:name="android.intent.action.MAIN" />
 <category android:name="android.intent.category.LAUNCHER" />
 </intent-filter>

Answer 3

我尝试了你的代码。它运行正常。我认为问题是因为内存不足。问题是图像资源，尝试以压缩格式设置图像以避免内存泄漏。

设置新内容视图时应用程序崩溃
