设置新的内容视图时，应用崩溃

Question

编辑：

看来我的按钮样式引起了问题。

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;
        }
    });

出于某些原因，以上代码适用于4.2及更高版本。

将其放在这里供将来的人们使用。

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，当我删除按钮样式时，错误消失了。

看来我在按钮上使用的样式是造成这种情况的原因。

<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出现的问题是Button的背景。我认为这是一个很大的形象，所以它溢出了您的记忆。

首先
尝试删除menu_system.xml中的任何@drawable，尤其是Button中的android：background。
如果可以运行，请运行，然后您知道要查找的位置。

第二（用于解决方法）
将背景图像文件
从drawable移至drawable-xhdpi的较大文件夹
