问题 Well, you might have seen few questions like asking for this. But reading all of those questions/answers and almost all of the android inputmethod webpages in Google, I am still in trouble. My final goal is to create a custom keyboard. But of course, mine will have special input methods for certain language. But this time, all I want is to show my custom view when the keyboard is popped up. I've managed to pop the default layout based on a qwerty.xml file, which is something like this. xml

Calling InputMethodManager.setInputMethod(IBinder token, String id) outside the InputMethodService. Where to find token?

阅读更多关于 Calling InputMethodManager.setInputMethod(IBinder token, String id) outside the InputMethodService. Where to find token?

I want to show Google Voice Typing IME on my EditText by clicking on Button. So, according to this article and source code I should write this code inputMethodManager.setInputMethodAndSubtype(IBinder token, String id, InputMethodSubtype subtype) The problem is: where to find appropriate token. In the source code I saw this mInputMethodService.getWindow().getWindow().getAttributes().token It works great, but this code located in InputMetodService superclass, so it has access to InputMethodService instance. But i don't (unfortunately :) ). Please tell me if you have any suggestions. Thanks. NOT

Recently while developing an app, I faced an issue. I have searched a lot on google but couldn't find any solution. In the end I came across this Android issue tracker To explain my issue, I have made a sample App. Basic Working of my Sample App I have a screen, which has an EditText, a Button and a RelativeLayout.

I'd like to detect finger being dragged over ImageView. I get my ImageView, create instances of GestureDetector and View.OnTouchListener, then set View.OnTouchListener to ImageView. OnTouchListener detects all touches ("touch occured") and I pass them to GestureDetector, but it never calls its methods onScroll or onFling. What I am doing wrong? Bellow you can see related source: myImageView = (ImageView) findViewById(R.id.imageView1); myGestureDetector = new GestureDetector(this, new GestureDetector.OnGestureListener() { @Override public boolean onSingleTapUp(MotionEvent e) { // TODO Auto

问题 Im trying to create an IME for android that is not a traditional keyboard (rows of keys corresponding to the different letters) and I am having trouble finding helpful resources on how to do so since all of the code examples in the SDK use a Keyboard API and it's built in functions. I've designed the interface of the IME in an XML file as though it were simply an Activity within in application but I'm getting lost in their demos since their Keyboards are simply objects that are built from a

阅读更多关于 Better way to get all the text in an EditText from an InputConnection?

问题 I've written an IME (InputMethodService) and I need to get all the text from the EditText it is editing. I know one way: InputConnection inputConnection = getCurrentInputConnection(); inputConnection.append(inputConnection.getTextBeforeCursor(9999, 0)) .append(inputConnection.getTextAfterCursor(9999, 0)); It works, but it seems pretty stupid and clunky. However there is no such method InputConnection.getText() . Is there a better way? P.S. I cannot access the EditText from my IME because it

How do I change the input method programatically?

阅读更多关于 How do I change the input method programatically?

I have a requirement of changing the keyboard based on the change of language. I have done a bit of research and found that it can be done using these APIs InputMethodManager setInputMethod(android.os.IBinder, java.lang.String) InputMethodService switchInputMethod(java.lang.String) For the 1st API, I need an IBinder token which can be taken from InputMethodService instance by calling mInputMethodService.getWindow().getWindow().getAttributes().token or if I have the reference to InputMethodService object I can simply call mInputMethodService.switchInputMethod(id) to change the input method.
