实现效果

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;

}

}

});
