我试图阅读USSD响应以获得Sim余额等,而且我遇到了问题,我一直在阅读与Stackoverflow相关的许多问题,到目前为止还没有任何工作。除此之外:Prevent USSD dialog and read USSD response?。来自@HenBoy331
但我仍然遇到问题。我的广播接收器也没有被调用。我使用的是4.4.2
但它没有显示任何内容。我似乎无法解析消息并获得平衡。
我有MainActivity
拨打电话,ReceiverActivity
实施广播接收器,USSDService
课程以获得USSD回复。
MainActivity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService(new Intent(this, USSDService.class));
dailNumber("100");
}
private void dailNumber(String code) {
String ussdCode = "*" + code + Uri.encode("#");
startActivity(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussdCode)));
}
}
RecieverActivity.java
public class RecieverActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
IntentFilter filter = new IntentFilter("com.times.ussd.action.REFRESH");
this.registerReceiver(new Receiver(), filter);
}
public class Receiver extends BroadcastReceiver {
private String TAG = "XXXX";
@Override
public void onReceive(Context context, Intent intent) {
String message = intent.getStringExtra("message");
Log.i(TAG, "Got message: " + message);
}
}
}
USSDService.java
public class USSDService extends AccessibilityService {
public String TAG = "XXXX";
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
Log.d(TAG, "onAccessibilityEvent");
AccessibilityNodeInfo source = event.getSource();
/* if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && !event.getClassName().equals("android.app.AlertDialog")) { // android.app.AlertDialog is the standard but not for all phones */
if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && !String.valueOf(event.getClassName()).contains("AlertDialog")) {
return;
}
if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED && (source == null || !source.getClassName().equals("android.widget.TextView"))) {
return;
}
if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED && TextUtils.isEmpty(source.getText())) {
return;
}
List<CharSequence> eventText;
if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
eventText = event.getText();
} else {
eventText = Collections.singletonList(source.getText());
}
String text = processUSSDText(eventText);
if( TextUtils.isEmpty(text) ) return;
// Close dialog
performGlobalAction(GLOBAL_ACTION_BACK); // This works on 4.1+ only
Log.d(TAG, text);
// Handle USSD response here
Intent intent = new Intent("com.times.ussd.action.REFRESH");
intent.putExtra("message", text);
sendBroadcast(intent);
}
private String processUSSDText(List<CharSequence> eventText) {
for (CharSequence s : eventText) {
String text = String.valueOf(s);
// Return text if text is the expected ussd response
if( true ) {
return text;
}
}
return null;
}
@Override
public void onInterrupt() {
}
@Override
protected void onServiceConnected() {
super.onServiceConnected();
Log.d(TAG, "onServiceConnected");
AccessibilityServiceInfo info = new AccessibilityServiceInfo();
info.flags = AccessibilityServiceInfo.DEFAULT;
info.packageNames = new String[]{"com.android.phone"};
info.eventTypes = AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED | AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED;
info.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;
setServiceInfo(info);
}
}
AndroidManifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

拜托,我有没有办法错误地实现这一点,或者有一种新方法可以获得有效的USSD回复?
答案 0 :(得分:0)
启动后,手动更改设置
设置 - &gt;辅助功能设置 - &gt;您可以看到“您的应用名称”选项。打开它。 (这必须作为应用程序流程的一部分(而不是手动))
