问题根源

你遇到的设备特异性问题，核心原因是部分定制ROM（如小米、华为等）为了隐私安全，限制了非前台应用的剪贴板访问权限。当启动分享选择器后，你的App退到后台失去焦点，系统会拒绝App的剪贴板监听请求，对应日志里的错误：

Denying clipboard access to package.name, application is not in focus neither is a system service for user 0

而原生Android或部分宽松权限的ROM，允许后台App监听剪贴板，所以不会触发该问题。

解决方案一：临时前台服务（无需用户额外授权）

通过启动一个低优先级的前台服务，让App保持“前台状态”权限，从而绕过系统对后台App的剪贴板限制。

1. 创建剪贴板监听前台服务

public class ClipboardMonitorService extends Service {
    private static final String CHANNEL_ID = "ClipboardMonitorChannel";
    private ClipboardManager.OnPrimaryClipChangedListener clipListener;

    @Override
    public void onCreate() {
        super.onCreate();
        // 适配Android O及以上的通知渠道
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "分享内容监听", NotificationManager.IMPORTANCE_LOW);
            NotificationManager manager = getSystemService(NotificationManager.class);
            manager.createNotificationChannel(channel);
        }

        ClipboardManager clipboardManager = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
        clipListener = () -> {
            try {
                if (clipboardManager.hasPrimaryClip() && clipboardManager.getPrimaryClip().getItemCount() > 0) {
                    CharSequence copiedData = clipboardManager.getPrimaryClip().getItemAt(0).getText();
                    // 将复制内容通过广播传递给主Activity
                    Intent intent = new Intent("com.your.package.CLIPBOARD_UPDATED");
                    intent.putExtra("copied_text", copiedData.toString());
                    sendBroadcast(intent);
                }
            } catch (Exception ex) {
                Log.e("ClipboardMonitor", "监听失败", ex);
            }
        };
        clipboardManager.addPrimaryClipChangedListener(clipListener);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 启动前台服务，显示低优先级通知（用户感知弱）
        Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID)
                .setSmallIcon(R.drawable.ic_notification)
                .setContentTitle("正在监听分享内容")
                .setContentText("完成操作后将自动停止")
                .setPriority(NotificationCompat.PRIORITY_LOW)
                .build();
        startForeground(1, notification);

        // 30秒后自动停止服务（可根据需求调整时长）
        new Handler(Looper.getMainLooper()).postDelayed(this::stopSelf, 30000);
        return START_NOT_STICKY;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        ClipboardManager clipboardManager = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
        clipboardManager.removePrimaryClipChangedListener(clipListener);
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

2. 修改分享方法，启动服务

public void share_text(String title, String subject, String text) {
    // 启动剪贴板监听服务
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        startForegroundService(new Intent(this, ClipboardMonitorService.class));
    } else {
        startService(new Intent(this, ClipboardMonitorService.class));
    }

    int requestCode = 111;
    Intent sharingIntent = new Intent(Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");
    sharingIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
    sharingIntent.putExtra(Intent.EXTRA_TEXT, text);

    PendingIntent pi = PendingIntent.getBroadcast(this, requestCode, new Intent(this, ShareBroadCast.class),
            PendingIntent.FLAG_MUTABLE | PendingIntent.FLAG_UPDATE_CURRENT);
    sharingIntent = Intent.createChooser(sharingIntent, title, pi.getIntentSender());

    startActivity(sharingIntent);
}

3. 在主Activity接收广播

private BroadcastReceiver clipboardUpdateReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String copiedText = intent.getStringExtra("copied_text");
        // 处理复制的文本逻辑
        Log.d(TAG, "复制内容: " + copiedText);
        // 收到内容后停止服务
        stopService(new Intent(context, ClipboardMonitorService.class));
    }
};

@Override
protected void onResume() {
    super.onResume();
    registerReceiver(clipboardUpdateReceiver, new IntentFilter("com.your.package.CLIPBOARD_UPDATED"));
}

@Override
protected void onPause() {
    super.onPause();
    unregisterReceiver(clipboardUpdateReceiver);
}

4. 注册服务到Manifest

<service android:name=".ClipboardMonitorService"
         android:foregroundServiceType="dataSync" />

解决方案二：无障碍服务（更稳定，但需用户授权）

如果前台服务方案仍有设备兼容问题，可使用无障碍服务——它拥有更高的系统权限，不受App焦点状态限制，但需要用户手动开启无障碍权限。

1. 创建无障碍服务

public class ClipboardAccessibilityService extends AccessibilityService {
    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        // 监听剪贴板变化事件
        if (event.getEventType() == AccessibilityEvent.TYPE_CLIPBOARD_CHANGED) {
            ClipboardManager clipboardManager = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
            if (clipboardManager.hasPrimaryClip() && clipboardManager.getPrimaryClip().getItemCount() > 0) {
                CharSequence copiedData = clipboardManager.getPrimaryClip().getItemAt(0).getText();
                Intent intent = new Intent("com.your.package.CLIPBOARD_UPDATED");
                intent.putExtra("copied_text", copiedData.toString());
                sendBroadcast(intent);
            }
        }
    }

    @Override
    public void onInterrupt() {}

    @Override
    protected void onServiceConnected() {
        super.onServiceConnected();
        AccessibilityServiceInfo info = new AccessibilityServiceInfo();
        info.eventTypes = AccessibilityEvent.TYPE_CLIPBOARD_CHANGED;
        info.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;
        setServiceInfo(info);
    }
}

2. 注册服务到Manifest

<service android:name=".ClipboardAccessibilityService"
         android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
    <intent-filter>
        <action android:name="android.accessibilityservice.AccessibilityService" />
    </intent-filter>
    <meta-data android:name="android.accessibilityservice"
               android:resource="@xml/accessibility_service_config" />
</service>

3. 创建无障碍配置文件（res/xml/accessibility_service_config.xml）

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeClipboardChanged"
    android:accessibilityFeedbackType="feedbackGeneric"
    android:accessibilityFlags="flagDefault"
    android:canRetrieveWindowContent="true"
    android:description="@string/accessibility_service_desc" />

4. 引导用户开启权限

private void requestAccessibilityPermission() {
    Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);
    startActivity(intent);
}
