• 匯入依賴

compile ‘io.reactivex:rxandroid:1.2.1’ 
compile ‘io.reactivex:rxjava:1.1.6’

• 新增許可權

//獲得寫sd卡的許可權
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
//獲得讀sd卡的許可權
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"><
 
/uses-permission>
//讀取網路的許可權
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

• 建立一個class類：MyOnSubscribe.java

public class MyOnSubscribe implements Observable.OnSubscribe<View> {

        public MyOnSubscribe(View view) {
            view.setOnClickListener(new
 
 View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    System.out.println("我被狂點中...");
                    //釋出通知
                    mSubscriber.onNext(view);
                }
            });
        }
        private Subscriber mSubscriber;

        @Override
        public
 
 void call(Subscriber<? super View> subscriber) {
            mSubscriber = subscriber;
        }
    }

• 在要寫點選事件的類中將點選事件換成下面的方法（這裡是button）

private void RxAndroidClick() {
//mButton是按鈕的物件
    Observable.create(new MyOnSubscribe(mButton))
      .throttleFirst(1, TimeUnit.SECONDS)
       .subscribe(new Action1<View>() {
           @Override
           public void call(View view) {
               System.out.println("我在call方法中,我被點選了,有反應了");
           }
         });
    }
