使用这段代码

   private ClipboardManager myClipboard;
   private ClipData myClip;
   TextView textView;
   Button copyText;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainpage);
    textView = (TextView) findViewById(R.id.textview);
    copyText = (Button) findViewById(R.id.bCopy);
    myClipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);

    copyText.setOnClickListener(new View.OnClickListener() {


        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub


           String text = textView.getText().toString();
           myClip = ClipData.newPlainText("text", text);
           myClipboard.setPrimaryClip(myClip);
           Toast.makeText(getApplicationContext(), "Text Copied", 
           Toast.LENGTH_SHORT).show(); 
        }
    });
}

就用这个。它只适用于android api >= 11之前，你必须使用一个ClipData。

ClipboardManager _clipboard = (ClipboardManager) _activity.getSystemService(Context.CLIPBOARD_SERVICE);
_clipboard.setText(YOUR TEXT);

希望对你有所帮助:)

(更新3/19/2015) 就像Ujjwal Singh说的，setText方法已经弃用了，你应该使用setPrimaryClip(clipData)，就像文档建议的那样

    String stringYouExtracted = referraltxt.getText().toString();
    android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getActivity().getSystemService(Context.CLIPBOARD_SERVICE);
    android.content.ClipData clip = android.content.ClipData.newPlainText("Copied Text", stringYouExtracted);

clipboard.setPrimaryClip(clip);
        Toast.makeText(getActivity(), "Copy coupon code copied to clickboard!", Toast.LENGTH_SHORT).show();

只需编写以下代码:

clipboard.setText(getstring);

使用Jetpack Compose，这非常简单:

AmbientClipboardManager.current.setText(AnnotatedString("Copied Text"))

在Android中复制任何文本:

            TextView text = findViewById(R.id.text_id);
            ImageView icons = findViewById(R.id.copy_icon);

            icons.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    ClipboardManager clipboardManager = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
                    ClipData clipData = ClipData.newPlainText("text whatever you want", text.getText().toString());
                    clipboardManager.setPrimaryClip(clipData);

                    Toast.makeText(context, "Text Copied", Toast.LENGTH_SHORT).show();
                }
            });
