Copy text from TextView on Android
提问by Erdal
I have a ListViewwhere each item is a TextView.
我有一个ListView，其中每个项目都是一个TextView.
I want to enable the long press behaviour similar to an EditTextthat displays the default context menu with items like "Select all", "Cut all", "Copy all", etc.
我想启用类似于EditText显示默认上下文菜单的长按行为，其中包含“全选”、“全部剪切”、“全部复制”等项目。
Is there an easy way to enable this for a TextView?
有没有一种简单的方法可以为 a 启用此功能TextView？

I think I have a solution.
Just callregisterForContextMenu(yourTextView);
我想我有一个解决方案。打电话就行registerForContextMenu(yourTextView);
and your TextViewwill be registered for receiving context menu events.
并且您TextView将注册接收上下文菜单事件。
Then override onCreateContextMenuin your Activity:
然后覆盖onCreateContextMenu你的Activity：
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
//user has long pressed your TextView
menu.add(0, v.getId(), 0, "text that you want to show in the context menu - I use simply Copy");
//cast the received View to TextView so that you can get its text
TextView yourTextView = (TextView) v;
//place your TextView's text in clipboard
ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
clipboard.setText(yourTextView.getText());
}
Hope this helps you and anyone else looking for a way to copy text from a TextView
希望这可以帮助您和其他任何正在寻找从文本复制文本的方法的人 TextView

Actually, you do not have to develop this feature by yourself. You just need to use EditText instead TextView, while you set the android:editable of EditText to false. My code is here:
实际上，您不必自己开发此功能。您只需要使用 EditText 而不是 TextView，同时将 EditText 的 android:editable 设置为 false。我的代码在这里：
R.layout.edittext.xml
R.layout.edittext.xml
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="40dip"
android:editable="false"
android:background="@null"
android:textColor="#FFFFFF"/>
ListItemCopyTextActivity.java
ListItemCopyTextActivity.java
public class ListItemCopyTextActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout ll = new LinearLayout(this);
ListView lv = new ListView(this);
String[] values = new String[15];
for (int i = 0; i < 15; i++) {
values[i] = "ListItem NO." + i;
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.edittext, values);
lv.setAdapter(adapter);
ll.addView(lv, LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
setContentView(ll);
}
}
You can just long click the item, and choose the select text, copy, cut, past etc.
您只需长按该项目，然后选择选择文本、复制、剪切、过去等。

To allow users to copy some or all of the TextView's value and paste it somewhere else,
为了允许用户复制部分或全部 TextView 的值并将其粘贴到其他地方，
set the XML attribute {@link android.R.styleable#TextView_textIsSelectable android:textIsSelectable}to "true"
将 XML 属性设置{@link android.R.styleable#TextView_textIsSelectable android:textIsSelectable}为"true"
or
或者
call {@link #setTextIsSelectable setTextIsSelectable(true)}.
打电话{@link #setTextIsSelectable setTextIsSelectable(true)}。

You might want to register an onItemLongClickListener on your ListView and then based on the selected item, provide the user with whatever options you choose.
您可能希望在 ListView 上注册一个 onItemLongClickListener，然后根据所选项目为用户提供您选择的任何选项。
