Android优雅地处理按钮重复点击的几种方法

App中，有很大一部分场景是点击按钮，向服务端提交数据，由于网络请求需要时间，用户很可能会多次点击，造成数据重复提交，造成各种莫名其妙的问题。

因此，防止按钮多次点击，是Android开发中一个很重要的技术手段。

以前的处理方式

网上查找到的，或者你可能会想到的方法大概有这些：

1.每个按钮点击事件中，记录点击时间，判断是否超过点击时间间隔

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

public class ClickActivity extends AppCompatActivity {       private long mLastClickTime = 0;     public static final long TIME_INTERVAL = 1000L;       @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_click);         findViewById(R.id.btn_button2).setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View view) {                 long nowTime = System.currentTimeMillis();                 if (nowTime - mLastClickTime > TIME_INTERVAL) {                     // do something                     mLastClickTime = nowTime;                 } else {                     Toast.makeText(ClickActivity.this, "不要重复点击", Toast.LENGTH_SHORT).show();                 }             }         });     } }

这种方式，每个点击事件都需要写一个时间判断，重复代码很多。

2.封装一个点击事件，处理点击间隔判断

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

public abstract class CustomClickListener implements View.OnClickListener{     private long mLastClickTime;     private long timeInterval = 1000L;       public CustomClickListener() {       }       public CustomClickListener(long interval) {         this.timeInterval = interval;     }       @Override     public void onClick(View v) {         long nowTime = System.currentTimeMillis();         if (nowTime - mLastClickTime > timeInterval) {             // 单次点击事件             onSingleClick();             mLastClickTime = nowTime;         } else {             // 快速点击事件             onFastClick();         }     }       protected abstract void onSingleClick();     protected abstract void onFastClick(); }

使用：

?

1 2 3 4 5 6 7 8 9 10 11

findViewById(R.id.btn_button).setOnClickListener(new CustomClickListener() {             @Override             protected void onSingleClick() {                 Log.d("xxx", "onSingleClick");             }               @Override             protected void onFastClick() {                 Log.d("xxx", "onFastClick");             }         });

　相比于第一种方式，这种方法将重复点击的判断封装在CustomClickListener内部，外部无需处理时间判断，只需要实现点击方法即可。　

3.利用RxAndroid处理重复点击

?

1 2 3 4 5 6 7 8

RxView.clicks(view)  .throttleFirst(1, TimeUnit.SECONDS)  .subscribe(new Consumer<Object () {   @Override   public void accept(Object o) throws Exception {    // do something   }   });

响应式地处理按钮点击，利用rxjava的操作符，来防止重复点击，相较于第1,2方案来说，此方法更为优雅一些。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42

public class ButtonUtils {       private static long lastClickTime = 0;     private static long DIFF = 1500;     private static int lastButtonId = -1;       /**      * 判断两次点击的间隔，如果小于1000，则认为是多次无效点击      *      * @return      */     public static boolean isFastDoubleClick() {         return isFastDoubleClick(-1, DIFF);     }       /**      * 判断两次点击的间隔，如果小于1000，则认为是多次无效点击      *      * @return      */     public static boolean isFastDoubleClick(int buttonId) {         return isFastDoubleClick(buttonId, DIFF);     }       /**      * 判断两次点击的间隔，如果小于diff，则认为是多次无效点击      *      * @param diff      * @return      */     public static boolean isFastDoubleClick(int buttonId, long diff) {         long time = System.currentTimeMillis();         long timeD = time - lastClickTime;         if (lastButtonId == buttonId && lastClickTime > 0 && timeD < diff) {             Log.v("isFastDoubleClick", "短时间内按钮多次触发");             return true;         }         lastClickTime = time;         lastButtonId = buttonId;         return false;     } }

　使用

?

1 2 3

if (!ButtonUtils.isFastDoubleClick(R.id.login_btn)) {//多次点击   }
