android中自定义loading的实现

在drawable中写一个animation的xml,当作imageview的background:

    android:oneshot="false" >

            android:drawable="@drawable/loading_1"
        android:duration="100"/>
            android:drawable="@drawable/loading_2"
        android:duration="100"/>
            android:drawable="@drawable/loading_3"
        android:duration="100"/>
            android:drawable="@drawable/loading_4"
        android:duration="100"/>
            android:drawable="@drawable/loading_5"
        android:duration="100"/>
            android:drawable="@drawable/loading_6"
        android:duration="100"/>
            android:drawable="@drawable/loading_7"
        android:duration="100"/>
            android:drawable="@drawable/loading_8"
        android:duration="100"/>
            android:drawable="@drawable/loading_9"
        android:duration="100"/>
            android:drawable="@drawable/loading_10"
        android:duration="100"/>
            android:drawable="@drawable/loading_11"
        android:duration="100"/>
            android:drawable="@drawable/loading_12"
        android:duration="100"/>

开始：

Animation anim = AnimationUtils.loadAnimation(getContext(), R.anim.loding);
  mLoading.setVisibility(View.VISIBLE);
  mLoading.startAnimation(anim);

结束：

VoiceToLayout.this.mLoading.clearAnimation();
