Question

我使用sdk创建一个“添加”按钮，所以当我按下“添加”按钮时我想把它移到左边，当我再按一次时回到原来的位置。我遇到的问题是按钮只能在按下时向左移动，并且在我再次按下它之后无法回到原来的位置。我在if ... else函数上遇到了什么问题吗？任何帮助都会很感激。

public class TestImage2 extends Activity {
/** Called when the activity is first created. */

ImageView image_plus;
ImageView image_subtract;
ImageView image_multiply;
ImageView image_div;

String op;

boolean pergi = false;
final  Animation animation = new TranslateAnimation(0,100,0,0);
final  Animation animation2 = new TranslateAnimation(100,0,0,0);

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    image_plus     = (ImageView)findViewById(R.id.test_image);     
    image_subtract = (ImageView)findViewById(R.id.test_image2);
    image_multiply = (ImageView)findViewById(R.id.test_image3);
    image_div      = (ImageView)findViewById(R.id.test_image4);

    image_plus.setOnClickListener(new OnClickListener(){

        public void onClick(View view) {

                if(pergi == false)
                {

                        animation.setDuration(1000);
                        image_plus.startAnimation(animation);
                        pergi= true;

                        animation.setFillAfter(true); 
                }
                else
                {

                        animation2.setDuration(1000);
                        image_plus.startAnimation(animation2);
                        pergi = false;
                        animation2.setFillAfter(true); 
                }
                }});

Answer 1

我认为

有问题

final  Animation animation2 = new TranslateAnimation(100,0,0,0);

应该是

final  Animation animation2 = new TranslateAnimation(0,-100,0,0);

：）

动画（移动）ImageView以一种方式工作，而不是另一种方式
