Android :: Custom Android Keyboard Input Filtering
Nov 24, 2009
I have an EditText that is to collect input for a basic calculator. I want to bring up the numeric keyboard, and thus I set android:inputType to numberDecimal|numberSigned. Problem is, the EditText filters out all characters that aren't numeric, such as "(", ")", "/", "*". I have tried overriding this behaviour by setting a custom InputFilter which filters nothing out, but it seems to have no affect on the EditText. Is there any way for me to display the numeric soft keyboard without the filtering behaviour?

Is is possible to get the virtual keyboard key events on a custom input field ? I tried using keyboardView, but somehow that doesn't work. Is it mandatory to use the android input method classes to get the events?

I would like to show a custom input field (specifically, one containing only 9-0 and two extra buttons containing decimal separator (, or .) and a delete button). I could create a custom IME, but (as far as I know) that would have to be set by the user as the system-wide input method. Is there a way to implement an input method and bind it to a specific input field?

I'm trying to filter my ListView which is populated with this ArrayAdapter:
CODE:............
However, when I call filter('test') on the filter nothing happens at all (or the background-thread is run, but the list isn't filtered as far as the user conserns).

I have a ListActivity based on an ArrayAdapter with setTextFilterEnabled set to true. This works fine on a device with a physical keyboard. When I start typing something on the keyboard, the items get filtered.My question is how to get the same behavior on a device with no physical keyboard?

If it was possible to use my physical keyboard to type, and have the android emulator simulate it as if it were a touch (specifically- the button highlights, and letter overlay)

I have a class that extends ImageView, which also handles keyboard input, currently via OnKeyListener, which works great with the 1.1 sdk, but how do I port this to the 1.5 sdk? How do I get the soft keyboard to load for this View? I haven't found a ton of documentation regarding the new input framework.

I'm working on a simple game: when you press a button on the screen, a character will run to certain direction. It's easy to support keyboard input. But, some phone doesn't go with a keyboard or even no a track ball. So I decided to draw a virtual "run" key on the screen (with opengl). When the user press the virtual key, I apply a velocity to the character. And when the user release the key, I disable the velocity to stop the character but there seems to be some touch event noisy. If my finger cannot press still, I will see millions of touch down and touch up events, instead of a single long pressing.
And occasionally, my program captured the touch down event when I touch the screen, but didn't capture touch up event. So my character will keep moving, even no finger is on the screen. I'm wondering if there is some way to reduce the touch event noisy and tell if the user is currently pressing on the screen, instead of only getting an event when touch up and down happen. It seems the system UI can detect long pressing, for example when you put a finger on one item of the list view widget, the entire item turns to orange. I just don't know how to detect pressing in my opengl game.

I am trying to develop a device which would attach to my Droid and send keystrokes to it, but I need help understanding how the USB OTG works. I have the basic pinout, but is there a reference and instruction set guide anywhere, preferably with example code? Has anyone had any luck developing similar peripherals?

I'm having a very very strange problem with input and textarea html tags in a WebView. Basically they never seem to gain input focus with the virtual keybaord. which shows a single input box. There is now way just tapping around the screen to get it to accept input. Strangely, if I use my trackball on my G1 to select the field, I can eventually get focus and type in it. For trackball-less things like the N1, that doesn't help though.

I'm developing and Android app using the 1.6 sdk. I'm using a TimePicker and I don't want the soft keyboard to come up when you click on the digits in the TimePicker. I only want the TimePicker to be changed using the plus and minus buttons. I've tried using android:focusable="false" and android:focusableInTouchMode="false" hoping those would do it, but they didn't seem to do anything. Is there a way to do this?

I was wondering if there was a way to add Japanese as an language input for the Android keyboard? By default, there is no option to add Japanese as a llanguage input, and all other keyboards that have it are either ugly, don't have ICS as an optional theme or just too much, I prefer the stock Android keyboard on ICS over anything else and I'm sure there are some of you that agree. It would be nice to have this and other possible languages as optional languages on this keyboard.

I want to implement a custom input method for certain EditTexts within my app. I understand I need to extend the InputMethodService class, but how do I then add this to certain views? I've tried just using the class name in the android:inputMethod XML property, but this seems not to work. Using the SoftKeyboard example in the 1.5 SDK, my manifest is as follows:..............

I'd like to show my own IME in the Select input method chooser dialog like the Japanese IME and the Chinese IME. How can I do that?
I am new to Android. I have tested Greek IME and other IME. Although .apk is successfully uploaded. But can't show in it and how to choose own IME from this place.
What do I need to do in my code?

I am trying to do something that I thought would be simple, yet I still haven't found the right approach. I have a Edit Text field that should only accept unsigned decimal entries. Using android:input Type="number Decimal" in my layout xml file achieves this, however the soft keyboard that is raised with this input Type is the standard keyboard but just uses the alternate view with the number row on top. This is far from ideal for a field that only allows numbers. A much better soft keyboard for numeric entry is the "phone" one. It has all of the numbers and a decimal. Perfect!! Well, except that for the life of me I cannot figure out how to use both the phone keyboard AND allow only numeric entry. I've tried everything I can think of but if I use the phone soft keyboard then the input field also allows things like "(" and any of the other symbols available on that keyboard. Is there any way to get the nice big numeric buttons of the phone keyboard along with only allowing decimal entry?

I am on a non rooted droid incredible. I have the newest version of the swype beta, and I noticed everytime I reboot my phone and I try to write something in swype the keyboard will just flash or something and it wont put in what I tried to write, and it will do this until I change my default input method back to the HTC keyboard and back to swype.

Inside TextView.java, I have the following code.
InputMethodManager imm = (InputMethodManager)getContext ().getSystemService(Context.INPUT_METHOD_SERVICE); Log.d("tag", " fullscreenmode test: " + imm.isFullscreenMode());
and also, InputMethodManager imm = InputMethodManager.peekInstance(); Log.d("tag", imm.isFullscreenMode());
My phone is in landscape mode. My application has an EditText. My keyboard(virtual/soft) is not visible. I expect the above codes (written inside TextView.java) to print false. But it prints true. How is that possible?

I wonder it is possible to know whether SIP is showing to user or not. A user application(Activity) can show or hide the Soft Input through the Input Method Manager. There is some APIs to handle the SIP. But I can't find API to know status of SIP(it is on showing or hiding).
When SIP is showing to user. It disturbs the UI of the Activity. So Activity should know about the information related with upper case. How can I know that?

I was wondering if it is possible to intercept keyboard input on a global level on Android. For example a user types in text into an edittext (does not matter which application) I would like to access said text to check for certain words. Is this even possible with Android's security model (yes I am aware this kind of feature could be used for various wrong things too).

I have a custom dialog displayed to input user info (ID). This appears on top of an activity with an 'Done' button, however when the edittext is selected and the soft keyboard appears, the keyboard obscures the Done button at the bottom of the dialog. The documentation / blog posts are a little dry on info specifically for dialogs, what do I need to include to get the dialog to pan up or otherwise?

I am attempting to learn Android development and have modified a sample app that loads a web page in a WebView. The web page contains a text input. I want to use the Android DatePicker to input a value instead of the keyboard. The code below almost works. The DatePicker is displayed but throws an unknown error when I select a date and call loadUrl on the WebView in the onDateSet handler to update the value of the text input (end of code sample). I suspect a cross thread issue but I'm not sure.
package com.freeze.android.hellowebview;
import java.util.Calendar;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.DatePicker;
public class HelloWebView extends Activity { WebView webview;
class DateJavaScriptInterface { public void pickDate() { showDialog(0);
} } public void loadScript(String script){
webview.loadUrl("javascript:(function() { " + script + "})()");
} private class HelloWebViewClient extends WebViewClient {
@Override public boolean shouldOverrideUrlLoading(WebView view, String url)
view.loadUrl(url); return true;
} @Override public void onPageFinished(WebView view, String url) {
loadScript("document.getElementById('trips_dateandtime').onfocus = function(
{this.blur();window.DateInterface.pickDate();};");
} } /** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new HelloWebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.addJavascriptInterface(new DateJavaScriptInterface(), "DateInterface");
webview.loadUrl("http://127.0.0.1:8000/mileage/default/index");
} @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
webview.goBack(); return true;
} return super.onKeyDown(keyCode, event);
} @Overrid protected Dialog onCreateDialog(int id) {
switch (id) { case 0:
final Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR);
int mMonth = c.get(Calendar.MONTH);
int mDay = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(this,
mDateSetListener, mYear, mMonth, mDay);
} return null;
} private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
@Overrid public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
loadScript("document.getElementById('trips_dateandtime').value = 'test';"); //ERROR
} };

I just got my HTC incredible yesterday from my preorder. I have problem to enable other keyboard such as Swype or others like Chinese input from google. I went to settings-keyboard & language and checked these keyboards, but when I typed text, only the default HTC touch input keyboard popped out, I did not find any key to switch. I did not find a way to disable the touch input keyboard either.

I live in Belgium, the Dutch part, and we use AZERTY keyboards here. My phone is in Dutch, but I could only choose "Dutch (The Netherlands)". In the Netherlands they speak dutch but use QUERTY. So, what I did was leave my phone in "Dutch (The Netherlands)", but I am using the French AZERTY keyboard.
The problem is, that the autocorrect now is also in French. When i typ a word the autocorrect shows a dutch suggestion, a french sugestion and an english suggestion. By default (pressing the spacebar) the phone chooses the French suggestion. Is there anyway to have an AZERTY keyboard and have the Dutch suggestion by default?
