通过代码（以编程方式）打开EditTextPreference
|
我已经使EditTextPreference \'textPasscode \'依赖于CheckBoxPreference \'checkBoxPasscode \'。我希望用户选中复选框后立即打开“ textPasscode”。甚至可以吗？
如果是，我可以在“ 0”功能中使用什么？
public void onSharedPreferenceChanged(SharedPreferences prefs, String key) {
if(key.contentEquals(\"checkBoxPasscode\")){
// ----some method to open edit text \"textPasscode\" ??
}
}
没有找到相关结果

public static EditText showInputDialog(Context context, OnClickListener clickListener, String message) { LayoutInflater factory = LayoutInflater.from(context); final View textEntryView = factory.inflate(R.layout.dialogedittext, null); final EditText editText = (EditText)textEntryView.findViewById(id.dialogEditText); final AlertDialog.Builder builder = new AlertDialog.Builder(context); builder .setTitle(message) .setView(textEntryView) .setPositiveButton(\"OK\", clickListener) .setNegativeButton(\"Cancel\", null).show(); return editText; }
