android-edittext

问题 I've looked into using a TextWatcher and an InputFilter , but I'm not too sure how to approach this problem. The idea is to have an EditText that inserts text from right to left. As the use input changes, I would like the following to occur. - User enters "1" -> Text formats as 00:01 - User enters "2" -> Text formats as 00:12 - User enters "8" -> Text formats as 01:28 How could I approach this? Inputfilter seems to be for excluding text and using setText inside the TextWatcher appears to run

问题 I have a ListView that contains two TextViews and one EditText in each row. I have searched and searched and cannot figure out how to get the text that the user enters into the EditText. My most recent attempt implements a TextWatcher. public void addIngredientToMeal(String ingredientName) { ingredient_list = (ListView) findViewById(R.id.ingredients_in_meal_listView); int numberOfIngredients = ingredient_list.getChildCount(); ListAdapter adapter = new ListAdapter(); adapter.name_array = new

问题 I am using a custom in-app keyboard, so I need to disable the system keyboard. I can do that with editText.setShowSoftInputOnFocus(false); for Android API 21+. But to do the same thing down to API 11, I am doing editText.setTextIsSelectable(true); Sometimes I want to show the system keyboard again after disabling it with setTextIsSelectable . But I can't figure out how. Doing the following does show the system keyboard, but if the user hides the keyboard and then clicks the EditText again,

问题 I have tried many options available online but none of them seem to be working. I have used this XML for this purpose. <android.support.design.widget.TextInputLayout android:layout_width="match_parent" android:layout_height="wrap_content" app:hintTextAppearance="@style/TextLabel"> <com.projects.fonts.RobotoEditText style="@style/EditText" android:hint="@string/description" android:singleLine="false" app:font="@string/roboto_regular" /> </android.support.design.widget.TextInputLayout> I have

问题 I am trying to create an EditText with auto-capitalization and auto-correction implemented. I have manually figured out how to add InputFilter s to allow auto-capitalization, though this only works after the first letter is typed, and I have had no luck with auto correction (I tried to create an InputFilter that used AutoText , but I'm not sure how all that works). Ideally, I could just use EditText.setInputType(...) to handle everything, but so far this has not worked. Is there a way to

问题 i am making a length converter which uses TextWatcher. the shortened code is v1.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { val1=Double.parseDouble(v1.getText().toString()); val2=InchToCm(val1); val3=InchToMl(val1); val4=InchToKm(val1); val5=InchToM(val1); val6=InchToY(val1); val7=InchToFt(val1); val8=InchToLg(val1)

问题 My custom replacement span works as long as text is not too long but as soon as text is longer than one line, span drawing completely breaks apart. My understanding is that draw() gets called twice in this case causing span to draw twice. There is no way to differentiate that second draw call from first one, giving you control over what to draw and where. start and end become useless as they report wrong values. Is ReplacementSpan supposed to even work for multiline text? I would appreciate

问题 I have been limiting the input to my edittext like this; InputFilter filter = new InputFilter() { public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) { String output = ""; for (int i = start; i < end; i++) { if (source.charAt(i)!='~'&&source.charAt(i)!='/') { output += source.charAt(i); } } return output; } }; But anyone who has used this method will know that it causes repeating characters when it is mixed with auto correct and the
