读取剪切板数据

调用时机 详情见AndroidQ(10)获取剪切板内容适配 - 简书 (jianshu.com)

Android 10以后需要获取焦点才能读到剪切板数据
@Override
 public void onWindowFocusChanged(boolean hasFocus) {
 }

数据获取

    public String getClipboardContent(Context context) {
        ClipboardManager cm = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
        if (cm != null) {
            ClipData data = cm.getPrimaryClip();
            if (data != null && data.getItemCount() > 0) {
                ClipData.Item item = data.getItemAt(0);
                if (item != null) {
                    CharSequence sequence = item.coerceToText(context);
                    if (sequence != null) {
                        return sequence.toString();
                    }
                }
            }
        }
        return "";
    }

清空剪切板

public void clearClipboard() {
        ClipboardManager cm = (ClipboardManager) mContext.getSystemService(Context.CLIPBOARD_SERVICE);
        if (cm != null) {
            cm.setPrimaryClip(ClipData.newPlainText(null, null));
        }
    }
