连点处理，禁止按钮在短时间内被多次点击

在做App的过程中，当点击某个按钮的时候，如果不做连点处理，会造成按钮在短时间内被点击多次的情况。

为了避免这种情况的发生，我们需要自定义一个抽象类 CustomClickListener 并继 View.OnClickListener

 1 abstract class CustomClickListener implements View.OnClickListener {
 2 
 3     private static final int MIN_CLICK_DELAY_TIME = 1000;    // 设置1秒内只能点击一次
 4 
 5     private long lastClickTime = 0;
 6 
 7     private int id = -1;
 8 
 9     @Override
10     public void onClick(View v) {
11         long currentTime = Calendar.getInstance().getTimeInMillis();
12         int mId = v.getId();
13         if (id != mId) {
14             id = mId;
15             lastClickTime = currentTime;
16             onNoDoubleClick(v);
17             return;
18         }
19         if (currentTime - lastClickTime > MIN_CLICK_DELAY_TIME) {
20             lastClickTime = currentTime;
21             onNoDoubleClick(v);
22         }
23     }
24 
25     protected abstract void onNoDoubleClick(View v);
26 
27 }

将连点处理写入到需要实现的类里面

 1 /**
 2  *
 3  * 控件中有一个按钮，一秒只能点击一次生效
 4  *
 5  */
 6 public class MainActivity extends AppCompatActivity {
 7 
 8     private Button button1;
 9 
10     @Override
11     protected void onCreate(Bundle savedInstanceState) {
12         super.onCreate(savedInstanceState);
13         setContentView(R.layout.activity_main);
14 
15         button1 = (Button)findViewById(R.id.button1);
16 
17         button1.setOnClickListener(new CustomClickListener(){
18             @Override
19             protected void onNoDoubleClick(View v) {
20                 Log.d("xiazhenjie","click

");
21             }
22         });
23     }
24 }
