RxBinding2.0的使用

简单介绍RxBinding2.0的使用，老套路，直接上代码

public class RxBindActivity extends AppCompatActivity {    private TextView mTextView;    private Button mButton;    private ListView mListView;    private EditText mEditText;    private CheckBox mCheckBox;    private ArrayAdapter<String> mArrayAdapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_rx_bind);        findId();        initView();        initListener();    }    private void findId() {        mTextView = (TextView) findViewById(R.id.tv_binding);        mEditText = (EditText) findViewById(R.id.et_binding);        mButton = (Button) findViewById(R.id.btn_binding);        mCheckBox = (CheckBox) findViewById(R.id.cb_binding);        mListView = (ListView) findViewById(R.id.lv_binding);    }    private void initView() {        mArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, testData());        mListView.setAdapter(mArrayAdapter);    }    private void initListener() {        //1).常规处理方式        RxView.clicks(mTextView).subscribe(v -> showToast("单机了mTextView"));        //2).3秒钟之内只取一个点击事件，防抖操作(用户快速的连续点击了好几下)        RxView.clicks(mButton).throttleFirst(3, TimeUnit.SECONDS)                .subscribe(v -> showToast("单机了mButton"));        //RxView.longClicks()长时间点击        //3).ListView的点击        RxAdapterView.itemClicks(mListView)                .subscribe(position -> showToast("单机了" + position));        //4).EditText数据改变的监听        RxTextView.textChanges(mEditText)                .debounce(600, TimeUnit.MILLISECONDS) //去除发送频率过快的项                .map(charSequence -> charSequence.toString()) //将监听到输入的数据转化为string                .subscribeOn(Schedulers.io())                .map(s -> {                            List<String> dataList = new ArrayList<>();                            if (!TextUtils.isEmpty(s)) {                                for (String testData : testData()) {                                    if (!testData.isEmpty() && testData.contains(s)) {                                        dataList.add(testData);                                    }                                }                                return dataList;                            }else {                                return testData();                            }                        }                ).observeOn(AndroidSchedulers.mainThread())                .subscribe(listData -> {                    mArrayAdapter.clear();                    mArrayAdapter.addAll(listData);                    mArrayAdapter.notifyDataSetChanged();                });        //5).CheckBox的监听        RxCompoundButton.checkedChanges(mCheckBox).subscribe(checkFlag -> {            mCheckBox.setChecked(checkFlag);            mButton.setBackgroundColor(checkFlag ? Color.GREEN : Color.RED);        });        //6)........    }    //模拟测试的数据    private List<String> testData() {        List<String> list = new ArrayList<>();        list.add("android");        list.add("math");        list.add("english");        list.add("pe");        list.add("sience");        return list;    }    private void showToast( String str) {         runOnUiThread(() -> Toast.makeText(RxBindActivity.this, str, Toast.LENGTH_SHORT).show());    }}

布局代码就省略了......
