布局
`<FrameLayout

android:layout_height="@dimen/dp_45" >
<Button

然后代碼中
loadingLogin = (LinearLayout) findViewById(R.id.login_loading_ll); loginIv = (ImageView) findViewById(R.id.login_loading); loginIv.setColorFilter(Color.WHITE);動(dòng)畫
Animation operatingAnim = AnimationUtils.loadAnimation(mContext, R.anim.image_rotate);login_button.setVisibility(View.GONE); loadingLogin.setVisibility(View.VISIBLE); loginIv.startAnimation(operatingAnim);登錄失敗
login_button.setVisibility(View.VISIBLE); loadingLogin.setVisibility(View.GONE); loginIv.clearAnimation();R.anim.image_rotate
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <rotate android:fromDegrees="0" android:toDegrees="359" android:duration="3000" android:repeatCount="-1" android:pivotX="50%" android:pivotY="50%" /> </set>
