可绘制的左图标变得不可见？

Question

我在edittext中添加了可绘制的左右图标。 Drawable正确用于显示或隐藏密码但是当我点击drawable右图标时，drawable left变得不可见。如何解决这个问题？

txtPassword.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_RIGHT = 2;

            if (event.getAction() == MotionEvent.ACTION_UP) {

                if (event.getRawX() >= (txtPassword.getRight() - txtPassword.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                    if (IsHidePwd) {
                        txtPassword.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ic_show_pwd, 0);
                        txtPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());

                        IsHidePwd = false;
                        return true;
                    } else {
                        txtPassword.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ic_hide_pwd, 0);
                        txtPassword.setTransformationMethod(HideReturnsTransformationMethod.getInstance());

                        IsHidePwd = true;
                        return true;
                    }
                }
            }
            return false;
        }
    });

在这一行中，我认为你还需要为左侧设置drawable。

txtPassword.setCompoundDrawablesWithIntrinsicBounds（R.drawable.left_img，0，R.drawable.ic_show_pwd，0）;
