TextWatcher() 的用法

标签：style   os   io   ar   for   art   cti   sp   log   

实例一：

phone_view.addTextChangedListener(new TextWatcher() {

});

实例二：

etSearch = (EditText)findViewById(R.id.etSearch);
etSearch.addTextChangedListener(searchWatcher);

TextWatcher searchWatcher = new TextWatcher() {

@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
if(chatHistoryAdapter != null){
chatHistoryAdapter.getFilter().filter(arg0);
}
}

@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}

@Override
public void afterTextChanged(Editable arg0) {
}
};

实例三：

editText1 = (EditText) findViewById(R.id.lin_search_edit);
editText1.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable edit) {
if (adapter != null) {
adapter.getFilter().filter(edit);
}
}
@Override
public void beforeTextChanged(CharSequence charsequence, int i,int j, int k) {
}
@Override
public void onTextChanged(CharSequence charsequence, int i, int j,int k) {
}
});

实例四：

        // 搜索的监听
        edit_input.addTextChangedListener(new TextWatcher() {
            public void onTextChanged(CharSequence s, int start, int before, int count) {
            }
            @Override
            public void afterTextChanged(Editable s) {
            if(adapter!=null)
            {
            adapter.getFilter().filter(s);
            }
           
            }
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {


            };
        });

实例五：

editText1.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable edit) {
if (adapter != null && isNeedFilter) {
adapter.getFilter().filter(edit);// Adapter类中实现Filterable方法，并且重写getFilter()
}
}


@Override
public void beforeTextChanged(CharSequence charsequence, int i,
int j, int k) {
}


@Override
public void onTextChanged(CharSequence charsequence, int i, int j,
int k) {
}
});

实例六：

meetingReplyMsg.addTextChangedListener(textWatcher);

/**
* TextWatcher
*/
TextWatcher textWatcher = new TextWatcher() {
@Override
public void afterTextChanged(Editable s) {
System.out.println("---s.toString()---:" + s.toString());
if (!Utils.isStrEmpty(s.toString())) {
Config._reply_msg.set(s.toString().trim());
}
}


@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}


@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
};

实例七：

mEdPhone.addTextChangedListener(new TextWatcher() {


@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}


@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}


@Override
public void afterTextChanged(Editable s) {
if (s.toString().length() > 0) {
mBtnRegister.setClickable(true);
mBtnRegister.setBackgroundResource(R.drawable.loginbtn);
} else if (s.toString().length() == 0) {
mBtnRegister.setClickable(false);
mBtnRegister
.setBackgroundResource(R.drawable.button_no_cliable);
}
mPhoneNumber = mEdPhone.getText().toString().trim();
}
});

实例八：

editText1.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable edit) {
if (adapter != null) {
adapter.getFilter().filter(edit);
}
}


@Override
public void beforeTextChanged(CharSequence charsequence, int i,
int j, int k) {
}


@Override
public void onTextChanged(CharSequence charsequence, int i, int j,
int k) {
}
});

实例九：

// 获取编辑框焦点
        editText.setFocusable(true);
        editText.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub

}

@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
 
}

@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
               editText.setSelection(s.length());
            Log.v("CustomDialog", "666666"+s.length());
}
});

实例十：

  searchBox = (EditText) view.findViewById(R.id.com_facebook_picker_search_text);


            searchBox.addTextChangedListener(new SearchTextWatcher());
            if (!TextUtils.isEmpty(searchText)) {
                searchBox.setText(searchText);
            }

    private class SearchTextWatcher implements 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) {
            onSearchBoxTextChanged(s.toString(), false);
        }


        @Override
        public void afterTextChanged(Editable s) {
        }
    }
