我正在尝试使用 AccessibilityService 访问我的 android 手机上的通知。

我尝试制作服务并从主要活动中调用它。我还为该服务添加了元数据。它不工作。我看不到服务的触发。

我正在使用 Android L 进行测试。在辅助功能设置中，我将我的应用程序“通知”添加为开启。

提前致谢。

我的主要活动

package com.example.tony.notify;

import android.content.Intent;
import android.provider.Settings;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
//        startActivityForResult(new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS), 0);
        Intent i = new Intent(this, MyAccessibilityService.class);
        startService(i);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

这是我的服务班

package com.example.tony.notify;

import android.accessibilityservice.AccessibilityService;
import android.accessibilityservice.AccessibilityServiceInfo;
import android.util.Log;
import android.view.accessibility.AccessibilityEvent;
import android.widget.Toast;

/**

public class MyAccessibilityService extends AccessibilityService {

    final String TAG = "Notification service";

    private String getEventType(AccessibilityEvent event) {
        switch (event.getEventType()) {
            case AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED:
                return "TYPE_NOTIFICATION_STATE_CHANGED";
            case AccessibilityEvent.TYPE_VIEW_CLICKED:
                return "TYPE_VIEW_CLICKED";
            case AccessibilityEvent.TYPE_VIEW_FOCUSED:
                return "TYPE_VIEW_FOCUSED";
            case AccessibilityEvent.TYPE_VIEW_LONG_CLICKED:
                return "TYPE_VIEW_LONG_CLICKED";
            case AccessibilityEvent.TYPE_VIEW_SELECTED:
                return "TYPE_VIEW_SELECTED";
            case AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED:
                return "TYPE_WINDOW_STATE_CHANGED";
            case AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED:
                return "TYPE_VIEW_TEXT_CHANGED";
        }
        return "default";
    }

    private String getEventText(AccessibilityEvent event) {
        StringBuilder sb = new StringBuilder();
        for (CharSequence s : event.getText()) {
            sb.append(s);
        }
        return sb.toString();
    }

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {

        Log.v(TAG, String.format(
                "onAccessibilityEvent: [type] %s [class] %s [package] %s [time] %s [text] %s",
                getEventType(event), event.getClassName(), event.getPackageName(),
                event.getEventTime(), getEventText(event)));

    }


    @Override
    public void onInterrupt() {

        Log.v(TAG, "onInterrupt");

    }

    @Override
    protected void onServiceConnected() {
        Toast.makeText(getApplicationContext(),"connected",Toast.LENGTH_SHORT).show();
        super.onServiceConnected();
        Log.v(TAG, "onServiceConnected");
        AccessibilityServiceInfo info = new AccessibilityServiceInfo();
        info.flags = AccessibilityServiceInfo.DEFAULT;
        info.eventTypes = AccessibilityEvent.TYPES_ALL_MASK;
        info.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;
        setServiceInfo(info);
    }
}

我声明服务的清单

我让它在 L 上工作，它并没有真正在 api 16 上工作，我在一个上测试过。任何人都可以建议添加使其适用于 api 14+

当我的小部件启用时，我已经这样做了：

@Override
public void onEnabled(Context context) {

    super.onEnabled(context);
    String enabledListeners = Settings.Secure.getString(
            context.getContentResolver(), "enabled_notification_listeners");
    if (!enabledListeners.contains("Myalert")) {
        Intent i = new Intent(
                "android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS");
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }

在我的清单中：

<service
        android:name="com.edgealert.NotificationMonitor"
        android:label="MyAlert"
        android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE" >
        <intent-filter>
            <action android:name="android.service.notification.NotificationListenerService" >
            </action>
        </intent-filter>
    </service>


    <receiver android:name=".MyReceiver" >
        <intent-filter>
            <action android:name="com.samsung.android.cocktail.action.COCKTAIL_UPDATE" />
        </intent-filter>

        <meta-data
            android:name="com.samsung.android.cocktail.provider"
            android:resource="@xml/single_cocktail" />
    </receiver>
