做这个项目我太累了我正在编写一个项目，该项目显示像 Facebook 这样的头部聊天但是当我将视图添加到窗口管理器时，它不会显示头部聊天并崩溃请帮帮我 MainActivity.java：

public class MainActivity extends AppCompatActivity 

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findViewById(R.id.start_bubble).setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View view) 
                startService(new Intent(MainActivity.this, ChatHeadService.class));
                finish();
            
        );

这是我的 ChatHeadService.java 代码：

public class ChatHeadService extends Service 

    private WindowManager mWindowManager;
    private View mChatHeadView;

    public ChatHeadService() 
    

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

    @Override
    public void onCreate() 
        super.onCreate();
        //Inflate the chat head layout we created
        mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        mChatHeadView = LayoutInflater.from(this).inflate(R.layout.layout_chat_head, null);

        //Add the view to the window.
        final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_PHONE,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                PixelFormat.TRANSLUCENT);

        //Specify the chat head position
        params.gravity = Gravity.TOP | Gravity.LEFT;        //Initially view will be added to top-left corner
        params.x = 0;
        params.y = 100;

        //Add the view to the window
        mWindowManager.addView(mChatHeadView, params);

        //Set the close button.
        ImageView closeButton = (ImageView) mChatHeadView.findViewById(R.id.close_btn);
        closeButton.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View v) 
                //close the service and remove the chat head from the window
                stopSelf();
            
        );

        //Drag and move chat head using user's touch action.
        final ImageView chatHeadImage = (ImageView) mChatHeadView.findViewById(R.id.chat_head_profile_iv);
        chatHeadImage.setOnTouchListener(new View.OnTouchListener()

                        //remember the initial position.
                        initialX = params.x;

你对我有什么建议吗？

[不知道为什么说我的帖子有太多代码，我来客它是因为日志所以我需要在这里写点东西]

【问题讨论】：

您发布的日志没有任何崩溃堆栈跟踪。将日志设置为错误模式，然后发布崩溃日志。好的，我会编辑帖子似乎没有任何错误。不知道为什么，但它关闭了应用程序并且没有出现任何头部聊天。顺便说一句，我认为这些信息会有所帮助 [另一个日志] \ I/ViewRootImpl@ffa9f53[MainActivity]:stopped(true) old=false I/ViewRootImpl@ffa9f53[MainActivity]: dispatchDetachedFromWindow \ 视频显示它是如何崩溃的：drive.google.com/file/d/1A5WI9vN6Mw2GzkQmuTK5QCRTPUy19yXa/… 【参考方案1】：

首先您需要验证目标设备，然后它才能工作。这是根据您的服务提供的示例代码，它可以正常工作。
