Я попытался создать этот класс сервисов ввода:
package sandhiflowers.game.com;
import android.inputmethodservice.InputMethodService;
import android.inputmethodservice.Keyboard;
import android.inputmethodservice.KeyboardView;
import android.text.TextUtils;
import android.view.View;
import android.view.inputmethod.InputConnection;
/**
* Created by vlado on 16.10.17.
*/
public class SandhiFlowersInputMethodService extends InputMethodService implements KeyboardView.OnKeyboardActionListener {
@Override
public View onCreateInputView() {
// get the KeyboardView and add our Keyboard layout to it
KeyboardView keyboardView = (KeyboardView) getLayoutInflater().inflate(R.layout.keyboard_view, null);
Keyboard keyboard = new Keyboard(this, R.xml.number_pad);
keyboardView.setKeyboard(keyboard);
keyboardView.setOnKeyboardActionListener(this);
return keyboardView;
}
@Override
public void onKey(int primaryCode, int[] keyCodes) {
InputConnection ic = getCurrentInputConnection();
if (ic == null) {
return;
}
switch (primaryCode) {
case Keyboard.KEYCODE_DELETE:
CharSequence selectedText = ic.getSelectedText(0);
if (TextUtils.isEmpty(selectedText)) {
// no selection, so delete previous character
ic.deleteSurroundingText(1, 0);
} else {
// delete the selection
ic.commitText("", 1);
}
ic.deleteSurroundingText(1, 0);
break;
default:
char code = (char) primaryCode;
ic.commitText(String.valueOf(code), 1);
}
}
@Override
public void onPress(int primaryCode) { }
@Override
public void onRelease(int primaryCode) { }
@Override
public void onText(CharSequence text) { }
@Override
public void swipeLeft() { }
@Override
public void swipeRight() { }
@Override
public void swipeDown() { }
@Override
public void swipeUp() { }
}И я получаю исключение класса:

Я предполагаю, что ваш родительский взгляд KeyboardViewдолжен быть LinearLayout, а не . Изменить:<LinearLayout android:layout_width="match_parent" android:layout_height="match_parent"> </LinearLayout>
<your.packages.KeyboardView
android:layout_width="match_parent"
android:layout_height="wrap_content">
</your.packages.KeyboardView>чтобы:
