BasicOnKeyboardActionListener

public class BasicOnKeyboardActionListener implements OnKeyboardActionListener {

    private Activity mTargetActivity;


    public BasicOnKeyboardActionListener(Activity targetActivity) {
        mTargetActivity = targetActivity;
    }

    @Override

自定义键盘 View .java

public class CustomKeyboardView extends KeyboardView {

    public CustomKeyboardView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public void showWithAnimation(Animation animation) {
        animation.setAnimationListener(new AnimationListener() {

            @Override
            public void onAnimationStart(Animation animation) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onAnimationRepeat(Animation animation) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                setVisibility(View.VISIBLE);
            }
        });

        setAnimation(animation);
    }

}

KeyboardWidgetActivity.java

public class KeyboardWidgetActivity extends Activity {

    private CustomKeyboardView mKeyboardView;
    private View mTargetView;
    private Keyboard mKeyboard;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);
        mKeyboard = new Keyboard(this, R.xml.keyboard);
        mTargetView = (EditText) findViewById(R.id.target);
        mTargetView.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                showKeyboardWithAnimation();
                return true;
            }
        });

        mKeyboardView = (CustomKeyboardView) findViewById(R.id.keyboard_view);
        mKeyboardView.setKeyboard(mKeyboard);
        mKeyboardView
                .setOnKeyboardActionListener(new BasicOnKeyboardActionListener(

    }


    private void showKeyboardWithAnimation() {
        if (mKeyboardView.getVisibility() == View.GONE) {
            Animation animation = AnimationUtils
                    .loadAnimation(KeyboardWidgetActivity.this,
                            R.anim.slide_in_bottom);
            mKeyboardView.showWithAnimation(animation);
        }
