单击EditText跳出“粘贴”

如图所示，单击EditText会跳出本该长按才会出现的“粘贴”按钮，求助各位大神们，怎么破？感激不尽！！！下面是代码

 public class DelEditText extends EditText {
    private Drawable imgClear;
    private Context mContext;

    public DelEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.mContext = context;
        init();
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    private void init() {
        imgClear = mContext.getResources().getDrawable(R.drawable.delete_gray);
        addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {
                setDrawable();
            }
        });
    }

    private void setDrawable() {
        if (length() < 1) {
            setCompoundDrawablesWithIntrinsicBounds(null, null, null, null);
        } else {
            setCompoundDrawablesWithIntrinsicBounds(null, null, imgClear, null);
        }
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (imgClear != null && event.getAction() == MotionEvent.ACTION_UP) {
            int eventX = (int) event.getRawX();
            int eventY = (int) event.getRawY();
            Rect rect = new Rect();
            getGlobalVisibleRect(rect);
            rect.left = rect.right - 100;
            if (rect.contains(eventX, eventY)) {
                setText("");
            }
        }
        return super.onTouchEvent(event);
    }

    protected void finalize() throws Throwable {
        super.finalize();
    }
}
