推荐答案
标准的方式,以避免多次点击是保存最后点击的时间,避免在1秒内(或时间跨度)其它按钮的点击。 示例 -
The standard way to avoid multiple clicks is to save the last clicked time and avoid the other button clicks within 1 second(or any time span). Example-
// Make ur activity class to implement View.OnClickListener
public class MenuPricipalScreen extends Activity implements View.OnClickListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
// setup listeners.
findViewById(R.id.imageView2).setOnClickListener(MenuPricipalScreen.this);
findViewById(R.id.imageView3).setOnClickListener(MenuPricipalScreen.this);
....
}
.
.
.
// variable to track event time
private long mLastClickTime = 0;
//View.OnClickListener.onClick method defination
@Override
public void onClick(View v) {
// Preventing multiple clicks, using threshold of 1 second
if (SystemClock.elapsedRealtime() - mLastClickTime < 1000) {
return;
}
mLastClickTime = SystemClock.elapsedRealtime();
// Handle button clicks
if (v == R.id.imageView2) {
// Do ur stuff.
}
else if (v == R.id.imageView2) {
// Do ur stuff.
}
...
}
