我正在尝试打开一个对话框窗口,但每次我尝试打开它都会抛出此异常:
Uncaught handler: thread main exiting due to uncaught exception
android.view.WindowManager$BadTokenException:
Unable to add window -- token null is not for an application
at android.view.ViewRoot.setView(ViewRoot.java:460)
at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:177)
at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:91)
at android.app.Dialog.show(Dialog.java:238)
at android.app.Activity.showDialog(Activity.java:2413)
我是通过showDialog显示器的id 调用来创建的.该onCreateDialog处理器记录良好,我可以通过它没有问题的一步,但因为它看起来像我想的东西我已经把它贴吧:
@Override
public Dialog onCreateDialog(int id)
{
Dialog dialog;
Context appContext = this.getApplicationContext();
switch(id)
{
case RENAME_DIALOG_ID:
Log.i("Edit", "Creating rename dialog...");
dialog = new Dialog(appContext);
dialog.setContentView(R.layout.rename);
dialog.setTitle("Rename " + noteName);
break;
default:
dialog = null;
break;
}
return dialog;
}
这有什么不足之处吗？有些问题在创建对话框时已经讨论过这个问题onCreate …
android runtimeexception android-dialog android-windowmanager
有很多关于这两种背景的帖子......但我仍然没有把它弄得恰到好处
据我所知到目前为止:每个都是它的类的一个实例,这意味着一些程序员建议你this.getApplicationContext()尽可能经常使用,以免"泄漏"任何内存.这是因为另一个this(获取Activity实例上下文)指向Activity每次用户倾斜手机或离开应用程序等时被销毁的内容.显然垃圾收集器(GC)没有捕获,因此使用太多内存..
但是,任何人都可以提出一些非常好的编码示例,它们是正确的使用this(获取当前Activity实例的上下文)并且应用程序上下文将是无用的/错误的吗？
当我尝试打开对话框时,我收到以下Android异常.有人可以帮我理解发生了什么,我该如何解决这个问题？

我似乎无法理解为什么会这样.这段代码:
mProgressDialog = ProgressDialog.show(this, "", getString(R.string.loading), true);
工作得很好.但是,这段代码:
mProgressDialog = ProgressDialog.show(getApplicationContext(), "", getString(R.string.loading), true);
抛出以下异常:

我的代码非常像这样:
public class classname1 extends Activity{
public void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.<view>);
//call the <className1> class to execute

是的,我试图使用getApplicationContext(),但这仍然是相同的错误
我提到了
使用getApplication()作为上下文抛出"无法添加窗口 - 令牌null不适用于应用程序"的对话框
Android:ProgressDialog.show()与getApplicationContext崩溃
Android 1.6:"android.view.WindowManager $ BadTokenException:无法添加窗口 - 令牌null不适用于应用程序"
最近我按照了如何创建警告对话框的教程,当我点击删除按钮时,它应该在删除之前向我显示警告,但它会崩溃.有人能告诉我我的错误在哪里吗？
以下是我的代码:
// Delete button click event
btnDeleteEvent.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// alerting user before deleting event
