android 加载数据等待动画,Android基础动画之--即时预约等待加载过程

思路：两张一样的图片从不同的点同时向一个方向移动

效果图如下：

public class CallActivity extends BaseActivity implements Animation.AnimationListener{

private static final String TAG = "CallActivity";

@BindView(R.id.iv_one)

ImageView iv_one;

@BindView(R.id.iv_two)

ImageView iv_two;

private TranslateAnimation animationFirst;

private TranslateAnimation animationSecond;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_call);

ButterKnife.bind(this);

initData();

startAnimation();

}

private void initData() {

animationFirst = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,1f,

Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f);

animationFirst.setDuration(5000);

animationFirst.setInterpolator(new LinearInterpolator());

animationFirst.setAnimationListener(this);

animationSecond = new TranslateAnimation(Animation.RELATIVE_TO_SELF,-1.0f,Animation.RELATIVE_TO_SELF,0f,

Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f);

animationSecond.setDuration(5000);

animationSecond.setInterpolator(new LinearInterpolator());

animationSecond.setAnimationListener(this);

}

private void startAnimation() {

iv_one.startAnimation(animationFirst);

iv_two.startAnimation(animationSecond);

}

@Override

public void onAnimationStart(Animation animation) {

}

@Override

public void onAnimationEnd(Animation animation) {

startAnimation();

}

@Override

public void onAnimationRepeat(Animation animation) {

}

}

布局文件(加载动画部分)

android:id="@+id/ll_progress"

android:layout_width="match_parent"

android:layout_height="@dimen/dp5"

>

android:id="@+id/iv_one"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:src="@drawable/scroll_img"

android:scaleType="fitXY"

/>

android:id="@+id/iv_two"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:src="@drawable/scroll_img"

android:scaleType="fitXY"

/>

最后吐槽有一个坑点，如果父布局用LinearLayout，则只有一个imageview有动画，用了RelativeLayout可以了，不知什么问题，有知道的可以告知一下，感激不尽
