如果我实际滑出我的Moto Droid A855上的键盘,它会崩溃我的测试应用程序,堆栈跟踪粘贴在下面.我不明白为什么？
此外,如果我用键盘启动我的应用程序,我的应用程序在启动时立即崩溃.
该应用程序包含一个活动,其中包含一个viewflipper作为主视图布局.取景器包含两个线性布局…

编辑：从主要活动添加XML布局和相关片段.

主要活动代码片段
/**

* TODO: make it work.
*/
@Override
public void onDetachedFromWindow() {
Log.d("Dash","OnDetachedFromWindow()");
try {
super.onDetachedFromWindow();
}
catch (Exception e) {
ViewFlipper v = (ViewFlipper)findViewById(R.id.vFlipper);
if (v != null) {
Log.d("Dash","De-Bug hit. e=" + e.getMessage());
v.stopFlipping();
}
}
}
解决方法
要解决这个问题,你必须
>定义一个名为MyViewFlipper的新类,它覆盖ViewFlipper(见下文)
>引用你以前引用过ViewFlipper的新类
>定义你的班级和布局,如下图所示：
新类叫MyViewFlipper.包含以下内容：
package com.gtosoft.dash; // change this to match your own app.
import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.ViewFlipper;
public class MyViewFlipper extends ViewFlipper {
public MyViewFlipper(Context context,AttributeSet attrs) {
super(context,attrs);
}
@Override
protected void onDetachedFromWindow() {
try{
super.onDetachedFromWindow();
}catch(Exception e) {
Log.d("MyViewFlipper","Stopped a viewflipper crash");
stopFlipping();
}
}
}
现在要使用这个“固定”版本的ViewFlipper,你必须在xml布局中引用它.由于它基本上是一个“自定义视图”,您必须完全限定MyViewFlipper的包路径,如下所示：
<com.gtosoft.dash.MyViewFlipper
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/vFlipper"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
(insert all the other old layout code here)
</com.gtosoft.dash.MyViewFlipper>
现在应用程序不再在键盘幻灯片事件中崩溃,或者应用程序是否已经从幻灯片开始.在日志中查找：
