我的DialogFragment出現問題。因此,爲了創建我的視圖,我使用了android博客中描述的方法。 這裏是我的DialogFragmentDialogFragment和強制顯示鍵盤
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View myLayout = inflater.inflate(R.layout.dialog_connect, null);
edit = (EditText) myLayout.findViewById(R.id.password_edit);
edit.requestFocus();
getDialog().getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);
return myLayout;
}
如果我使用onCreateView(),它的工作原理,但我想創造一個AlterDialog而要做到這一點,我有以下代碼:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
callback.onYesConnectClick(edit.getText().toString());
}
})
.setNegativeButton(R.string.refuse, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
callback.onNoConnectClick();
}
});
return builder.create();
}
如果我評論了代碼從onCreateView(),該應用程序的作品,但我不能強制鍵盤顯示,如果我取消onCreateView(),我得到一個崩潰。 這裏是堆棧跟蹤:

所以我的問題==>我可以使用AlertDialog和顯示鍵盤出現的對話框的時候?
wtf?!我期待了這麼多時間,解決方案非常簡單!然而,有一件事我不明白。我試圖在清單中設置android:windowSoftInputMode =「stateVisible」,它是負責啓動對話框的活動,它不起作用... – mrroboaat
謝謝!在StackOverflow上有大約一打「解決方案」來解決這個問題,並且它們都不適合我......但是這樣做。 – josh2112
這似乎是我所能找到的最有效的解決方案。我很好奇爲什麼必須在onActivityCreated而不是onResume()中調用?我非常喜歡聽到一些解釋。 – Sean
