[英]Android: AlertDialog with EditText does not automatically show the Keyboard
我有一個連續兩次顯示的AlertDialog。 在Nexus S上,一切都按照我的預期運行,但在Wildfire上鍵盤消失,第二次顯示Dialog時。
它必須是一些計時問題,因為鍵盤顯示,當我在構造函數中放置一個斷點並從那里繼續。 也許onFocusChange不是確保鍵盤顯示的正確位置。
我該如何解決? 為了找到這個問題背后的原因,你會尋找什么?
/**
* Show a dialog asking the user to confirm the PIN.
*/
private static abstract class PinConfirmationDialog extends AlertDialog {
protected PinConfirmationDialog(Context context, final int titleResource) {
super(context);
setTitle(titleResource);
// Set an EditText view to get user input
final EditText input = new EditText(context);
InputFilter[] FilterArray = new InputFilter[1];
FilterArray[0] = new InputFilter.LengthFilter(4);
input.setFilters(FilterArray);
input.setKeyListener(DigitsKeyListener.getInstance(false,true));
input.setInputType(InputType.TYPE_CLASS_NUMBER
| 16 /*InputType.TYPE_NUMBER_VARIATION_PASSWORD Since: API Level 11*/);
input.setTransformationMethod(new PasswordTransformationMethod());
setView(input);
setButton(context.getString(R.string.okay_action), new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
onOkButtonClicked(input.getText().toString());
}
});
setButton2(context.getString(R.string.cancel_action), new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
onCancelButtonClicked();
}
});
input.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}
}
});
}
/**
* OK Button was pressed
* @param pinCode The code the user has entered
*/
abstract void onOkButtonClicked(String pinCode);
/**
* Override method if needed
*/
protected void onCancelButtonClicked() {
}
}
嘗試這個 :
// Setting of the Keyboard
InputMethodManager imm = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
// For SHOW_FORCED
imm.showSoftInput ( YOUEDITTEXT, InputMethodManager.SHOW_FORCED);
希望它能幫到你!
你可以試試這個,
editText.setFocusable(true);
requestfocus();
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.hideSoftInputFromWindow(editText.getWindowToken(), 0);
