When you click a button during App creation, if you do not perform the link processing, the button will be clicked multiple times in a short time.

To avoid this situation, we need to customize an abstract class CustomClickListener and follow View. OnClickListener

Abstract class CustomClickListener implements View. onClickListener {private static final int MIN_CLICK_DELAY_TIME = 1000; // you can only click private long lastClickTime = 0 once in 1 second; private int id =-1; @ Override public void onClick (View v) {long currentTime = Calendar. getInstance (). getTimeInMillis (); int mId = v. getId (); if (id! = MId) {id = mId; lastClickTime = currentTime; onNoDoubleClick (v); return;} if (currentTime-lastClickTime> MIN_CLICK_DELAY_TIME) {lastClickTime = currentTime; onNoDoubleClick (v );}} protected abstract void onNoDoubleClick (View v );}

 

This document uses the Data-Binding framework. So is added under build. gradle (Module: app ).

android {    ...    dataBinding {        enabled = true    }}

 

Write the connection processing into the class to be implemented

Public class MainActivity extends AppCompatActivity {private ActivityMainBinding mBinding; @ Override protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); mBinding = DataBindingUtil. setContentView (this, R. layout. activity_main); mBinding. btn. setOnClickListener (new CustomClickListener () {@ Override protected void onNoDoubleClick (View v) {// TODO: the operation you want to perform }});}}
