在我的應用程序中,我有一個自定義AlertDialog(由系統使用showDialog()處理),其中包含一個帶有2個選項卡的tabhost。在其中一個標籤是一個微調。只要微調控制器未打開,我就可以旋轉屏幕而不會出現任何問題(顯示微調對話框)。如果旋轉器中打開時,我得到這個:當自定義alertdialog具有打開的微調器時,處理方向更改的正確方法是什麼?

所以......
1 - 是否可以在onPause()
以編程方式關閉微調?
2 - 我應該使用不同的方法嗎?
3 - 如果沒有合適的解決方案,我該如何捕獲這個特殊的異常? (我知道不好的做法,但是崩潰需要停止,並且由於活動在被破壞後重建自己,反正也不重要。
......請爲所有聖潔的愛,不建議我加android:configChanges="orientation"
到我的活動宣言。我非常驚訝的是如何經常爲正式修復,所有方向的問題。
編輯,瞭解更多信息
這裏是我的對話框創建代碼供參考:
static final int ID_DIALOG_CHOOSER = 1;
int pref_location;
private Dialog dialog;
...
protected Dialog onCreateDialog(int id)
{
switch(id)
{
case ID_DIALOG_CHOOSER:
dialog = show(ID_DIALOG_CHOOSER);
break;
}
return dialog;
}
...
showDialog(DialogView.ID_DIALOG_CHOOSER);
...
Dialog show(final int dialogType)
{
if (dialogType == ID_DIALOG_CHOOSER)
{
AlertDialog.Builder builder = new AlertDialog.Builder(this);
// inflate tabhost layout
View tabHostLayout = (View) inflater.inflate(R.layout.tabhost_layout, null);
FrameLayout tabContent = (FrameLayout) tabHostLayout.findViewById(android.R.id.tabcontent);
// inflate tab content layouts and add to tabhost layout
LinearLayout tab1 = (LinearLayout) inflater.inflate(R.layout.dialog_tab1, null);
tabContent.addView(tab1);
LinearLayout tab2 = (LinearLayout) inflater.inflate(R.layout.dialog_tab2, null);
tabContent.addView(tab2);
// tab setup
TabHost tabHost = (TabHost) tabHostLayout.findViewById(R.id.TabHost_Dialog_Tabs);
tabHost.setup();
TabHost.TabSpec tab_1 = tabHost.newTabSpec("Category 1");
tab_1.setContent(R.id.LinearLayout_Dialog_Tab1_Content);
tab_1.setIndicator(this.getResources().getString(R.string.dialog_tab1), this.getResources().getDrawable(R.drawable.tabhost_icon_selector));
tabHost.addTab(tab_1);
TabHost.TabSpec tab_2 = tabHost.newTabSpec("Category 2");
tab_2.setContent(R.id.LinearLayout_Dialog_Tab2_Content);
tab_2.setIndicator(this.getResources().getString(R.string.dialog_tab2), this.getResources().getDrawable(R.drawable.tabhost_icon_selector));
tabHost.addTab(tab_2);
// spinner setup
final Spinner spinner_location = (Spinner) tab1.findViewById(R.id.Spinner_Dialog_Location);
String[] locationArrayVals = null;
ArrayAdapter<CharSequence> adapter_location = null;
locationArrayVals = this.getResources().getStringArray(R.array.location_array_vals);
adapter_location = ArrayAdapter.createFromResource(this, R.array.location_array_listdisplay, android.R.layout.simple_spinner_item);
adapter_location.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_location.setAdapter(adapter_location);
// ok button
Button button_ok = (Button) tab1.findViewById(R.id.Button_Dialog_OK);
button_ok.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view)
{
pref_location = spinner_location.getSelectedItemPosition();
dialog.dismiss();
}
});
// create dialog
builder.setTitle("Location")
.setView(tabHost)
.setCancelable(true);
dialog = builder.create();
}
return dialog;
}
編輯與暫時的解決辦法
對於任何有興趣,我設法通過繼承微調和壓倒一切的onDetachedFromWindow()
像這樣至少停止崩潰:
public static class CatchingSpinner extends Spinner
{
public CatchingSpinner(Context context, AttributeSet attrs)
{
super(context, attrs);
}
@Override
protected void onDetachedFromWindow()
{
try
{
super.onDetachedFromWindow();
}
catch (IllegalArgumentException e)
{
// do whatever
}
}
}
就像我說的,一個解決辦法。仍在研究解決方案。 :/
你嘗試這個方法:的ShowDialog(DIALOG_PAUSED_ID);在對話框教程中提到:http://developer.android.com/guide/topics/ui/dialogs.html – ania
是的 - 我的對話框由活動管理。 – wirbly
可以提供用於顯示和解除對話框的代碼嗎?如果你說你使用dialog.dismiss(),那麼你不是使用yourActivity.showDialog(DIALOG_NAME)方法,而是使用dialog.show()。 – ania
