1. 使用ContextMenu

   （1）注册菜单

@Override

    public void onCreate(Bundle savedInstanceState) {

mMoblieTextView = (TextView) findViewById(R.id.mobile_textview);

//注册上下文菜单

  registerForContextMenu(mMoblieTextView);

}

    （2）onCreateContextMenu添加菜单

@Override

public void onCreateContextMenu(ContextMenu menu, View v,

ContextMenuInfo menuInfo) {

// TODO Auto-generated method stub

super.onCreateContextMenu(menu, v, menuInfo);

//在上下文菜单选项中添加选项内容

        //add方法的参数：add(分组id,itemid, 排序, 菜单文字)

menu.add(0, 0, 0, "复制电话号码");

}

       （3）点击事件响应

@Override

public boolean onContextItemSelected(MenuItem item) {

// TODO Auto-generated method stub

if (item.getItemId() == 0) {

if (null == clipboard) {

clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);

       }

// Creates a new text clip to put on the clipboard

       ClipData clip = ClipData.newPlainText("simple text",mMoblieTextView.getText());

       // Set the clipboard's primary clip.

       clipboard.setPrimaryClip(clip);

return true;

}

return super.onContextItemSelected(item);

}

2.使用OnLongClickListener 弹出 PopupWindow实现

（1）OnLongClickListener事件响应

 PopupWindow PopupmenuCopy;

 // 帮助窗口

    TextView mPopUpBtn;

@Override

    public void onCreate(Bundle savedInstanceState) {

mMoblieTextView = (TextView) findViewById(R.id.mobile_textview);

mMoblieTextView.setOnLongClickListener(new View.OnLongClickListener() {

@Override

public boolean onLongClick(View v) {

// TODO Auto-generated method stub

popupCopy();

return false;

}

});

}

（2）创建窗口

private void popupCopy() {

LayoutInflater layoutInflater = (LayoutInflater) mContext

.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

View layoutView = layoutInflater.inflate(

R.layout.popup_copy, null);

// Creating the PopupWindow

RelativeLayout popLayout = (RelativeLayout) layoutView

.findViewById(R.id.popLayout);

scaleFontSize(popLayout);

PopupmenuCopy = new PopupWindow(mContext);

PopupmenuCopy.setContentView(layoutView);

PopupmenuCopy.setWidth(LayoutParams.WRAP_CONTENT);

PopupmenuCopy.setHeight(LayoutParams.WRAP_CONTENT);

PopupmenuCopy.setBackgroundDrawable(getResources().getDrawable(

                R.drawable.left_drawer_item_bg));

PopupmenuCopy.setFocusable(true);// 点击空白处时，隐藏掉pop窗口

PopupmenuCopy.setOutsideTouchable(true);

mPopUpBtn  = (TextView) layoutView.findViewById(R.id.popbtn);

// 帮助页面按钮事件响应

mPopUpBtn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

if (null == clipboard) {

clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);

       }

// Creates a new text clip to put on the clipboard

       ClipData clip = ClipData.newPlainText("simple text",mMoblieTextView.getText());

       clipboard.setPrimaryClip(clip);

       PopupmenuCopy.dismiss();

}

});

int[] location = new int[2];  

mMoblieTextView.getLocationOnScreen(location);

PopupmenuCopy.showAtLocation(mMoblieTextView,Gravity.NO_GRAVITY, location[0],location[1]+mMoblieTextView.getHeight());

//控件上方

//PopupmenuCopy.showAtLocation(mMoblieTextView,Gravity.NO_GRAVITY, location[0], location[1]-PopupmenuCopy.getHeight());

}

  （3）popup_copy布局文件

    android:id="@+id/popLayout"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:background="@color/transparent"

     >

        android:id="@+id/popbtn"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:padding="8dp"

        android:text="@string/copy_mobileID"

        android:textSize= "@dimen/add_item_text_size"

        android:background="@drawable/btn_copy_selector"

        android:textColor="@color/black"

        android:gravity="center"

        android:layout_centerInParent="true"

        />

3.使用使用OnLongClickListener 弹出 QuickAction实现

QuickAction mQuickAction;

 mMoblieTextView.setOnLongClickListener(new View.OnLongClickListener() {

@Override

public boolean onLongClick(View v) {

// TODO Auto-generated method stub

mQuickAction.show(v);

return false;

}

});

 ActionItem copyItem =       new ActionItem(0, getString(R.string.copy_mobileID));

          mQuickAction = new QuickAction(mContext);

          mQuickAction.addActionItem(copyItem);

        //setup the action item click listener

    mQuickAction.setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() {

    @Override

    public void onItemClick(QuickAction quickAction, int pos, int actionId) {

           switch (actionId) {

         case 0:

         if (null == clipboard) {

    clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);

           }

           ClipData clip = ClipData.newPlainText("simple text",mMoblieTextView.getText());

           clipboard.setPrimaryClip(clip);

               break;

             default:

               break;

           }          

    }

    });
