问题
I am working on a Custom Keyboard App. I need to set different themes for keys or background color in KeyboardView class and get key color at onCreateInputView() in SoftKeyboard extends InputMethodService Class.
However I am not getting how to get particular key according to keycode so I can change color or background of particular key.
回答1:
On any diffrent input layout use android:keyBackground=".."
example:
input.xml:
<com.example.KeyboardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/keyboard"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:keyBackground="@drawable/blue_key"
/>
input1.xml:
<com.example.KeyboardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/keyboard"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:keyBackground="@drawable/red_key"
/>
then on OnCreateInputView method:
@Override public View onCreateInputView() {
if(theme == 1)
mInputView = (KeyboardView) getLayoutInflater().inflate(R.xml.input , null);
else
mInputView = (KeyboardView) getLayoutInflater().inflate(R.xml.input1 , null);
mInputView.setOnKeyboardActionListener( this);
mInputView.setKeyboard(mQwertyKeyboard);
mComposing.setLength(0);
return mInputView;
}
and on the end of the method onStartInput add this:
setInputView(onCreateInputView());
If you've already done it and what you need is to set a different background to special keys. Maybe the solution to my problem that I wrote will help you: https://stackoverflow.com/a/18354298/2683898
