Android解决button反复点击问题

public class BaseActivity extends Activity {    

    protected boolean isDestroy;
    //防止反复点击设置的标志。涉及到点击打开其它Activity时。将该标志设置为false。在onResume事件中设置为true
    private boolean clickable=true;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        isDestroy=false;
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        isDestroy=true;

    }

    @Override
    protected void onResume() {
        super.onResume();
        //每次返回界面时，将点击标志设置为可点击
        clickable=true;
    }

    /**
     * 当前能否够点击
     * @return
     */
    protected boolean isClickable(){
        return  clickable;
    }

    /**
     * 锁定点击
     */
    protected void lockClick(){
        clickable=false;
    }

    @Override
    public void startActivityForResult(Intent intent, int requestCode, Bundle options) {
        if(isClickable()) {
            lockClick();
            super.startActivityForResult(intent, requestCode,options);
        }
    }
