//编辑框监听
            editText.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    
                }
    
                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {
    
                }
    
                @Override
                public void afterTextChanged(Editable s) {
    
                }
            });
            //编辑自动提示框
            autoCompleteTextView.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    
                }
    
                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {
    
                }
    
                @Override
                public void afterTextChanged(Editable s) {
    
                }
            });
            //Button和ImageButton，一样
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
    
                }
            });
            imageButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
    
                }
            });
            //复选框,注意和单选框接口二者区别
            checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    
                }
            });
            //单选框
            radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(RadioGroup group, int checkedId) {
    
                }
            });
            //下拉列表
            spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    
                }
    
                @Override
                public void onNothingSelected(AdapterView<?> parent) {
    
                }
            });
            //listView的Item监听
            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    
                }
            });
            //listView滑动监听
            listView.setOnScrollListener(new AbsListView.OnScrollListener() {
                @Override
                public void onScrollStateChanged(AbsListView view, int scrollState) {
    
                }
    
                @Override
                public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
    
                }
            });
