Android支持单词提示搜索框的网络请求策略

android:

管理类代码如下:

public class KapSearchRunnableHelper implements Runnable {    private Runnable runnable = null;    public KapSearchRunnableHelper(Runnable able){        runnable = able;    }    private KapSearchRunnableHelper(){}//私有化    Handler handler = new Handler();    public void pushKeyWord(){        handler.removeCallbacks(this);// 移除请求        handler.postDelayed(this,500);// 添加请求    }    @Override    public void run() {        //此处发起Http请求        runnable.run();    }}

使用如下:

final KapSearchRunnableHelper searchRunnableHelper = new KapSearchRunnableHelper(new Runnable() {            @Override            public void run() {                postList(0);//网络请求            }        });        editText.addTextChangedListener(new TextWatcher() {            @Override            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {            }            @Override            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {                //防止铺天盖地的请求 SearchRunnable管理                searchRunnableHelper.pushKeyWord();            }            @Override            public void afterTextChanged(Editable editable) {            }        });
