Android Action Bar search 搜尋

前陣子製作側邊欄，參考[Android]使用 Navigation Drawer 製作側選單(1)與[Android]使用 Navigation Drawer 製作側選單(2) ，由於上方有個ActionBar，在這裡面介紹的是按鈕，由於想用類似搜尋功能，於是稍作修改，主要修改地方為"Action Button 建立及點選事件"
1.在資料夾res->menu->main.xml修改

2.在資料夾res->layout->建立search_layout.xml 一個編輯，一個按鈕

3.MainActivity.java修改

 private EditText searchName;
 private String searchObject;
 private Button searchButton;

 // ================================================================================
 // Action Button 建立及點選事件
 // ================================================================================
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.main, menu);
  View v = (View) menu.findItem(R.id.action_search).getActionView();
  //文字編輯部分
  searchName = (EditText) v.findViewById(R.id.search);
  searchName.addTextChangedListener(new TextWatcher() {
   @Override
   public void afterTextChanged(Editable s) {
    // 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 onTextChanged(CharSequence s, int start, int before,
     int count) {
    // TODO Auto-generated method stub
    try {
     searchObject = searchName.getText().toString(); // 取得輸入文字
    } catch (Exception e) {

    }

   }
  });
  //送出部分
  searchButton = (Button) v.findViewById(R.id.searchGo);
  searchButton.setOnClickListener(new Button.OnClickListener() {
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    goSearch(); //要做甚麼
   }
  });

  return true;
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {

  // home
  if (drawerToggle.onOptionsItemSelected(item)) {
   return true;
  }

  // action buttons
  switch (item.getItemId()) {
  //用不到，刪掉
  default:
   break;
  }

  return super.onOptionsItemSelected(item);
 }

 void goSearch() {
  if (searchObject == null) {
  //搜尋空值，不做事
  } else {
   Intent intent = new Intent(this, xxxx.class); //前進至xxxx頁面
   intent.putExtra("searchName", searchObject); //傳值
   startActivity(intent); //啟動出發
  }
 }
