Android的未决意图不会被调用构件内 [英] Android pending intent not being called within widget
本文介绍了Android的未决意图不会被调用构件内的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
像这个问题（接受的答案），我想从我的应用程序的部件之一，推出语音识别。我成功地设法打开对话框，要求语音输入与此code里面的的onUpdate（）控件的方法：
//这个意图指向应该处理结果的活动，不工作
意图activityIntent =新意图（SoulissApp.getAppContext（），WrapperActivity.class）;
//不能正常工作，以及
//activityIntent.setComponent(new单元名（it.angelic.soulissclient，it.angelic.soulissclient.WrapperActivity））;
//这个意图包装效果的活动意图
的PendingIntent resultsPendingIntent = PendingIntent.getActivity（SoulissApp.getAppContext（），0，activityIntent，0）; //这个意图调用语音识别
意图voiceIntent =新意图（RecognizerIntent.ACTION_RECOGNIZE_SPEECH）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_LANGUAGE_MODEL，RecognizerIntent.LANGUAGE_MODEL_FREE_FORM）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_PROMPT，语音识别演示）;
voiceIntent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT，resultsPendingIntent）; 捆绑fakeBun =新包（）;
fakeBun.putChar（假货，F）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT_BUNDLE，fakeBun）; //这个意图包装语音识别意图，作品
的PendingIntent pendingInt = PendingIntent.getActivity（上下文，0，voiceIntent，0）;
updateViews.setOnClickPendingIntent（R.id.button1，pendingInt）;
语音识别工作，但是在识别过程结束后，我的 resultsPendingIntent 不叫。为什么呢？
从SYS日志中，我读到这样的：
... I / ActivityManager：开始U0 {CMP = it.angelic.soulissclient / .SoulissWidgetVoice（有临时演员）}从UID 10152陈列0 ......
而我期望这样的：
... I / ActivityManager：开始U0 {CMP = it.angelic.soulissclient / .WrapperActivity（有临时演员）} ...
而 SoulissWidgetVoice 是Widget类
由于 .WrapperActivity 正在等待意图。需要注意的是 WrapperActivity 本身可以从其他活动的正确启动，这是一个 Theme.NoDisplay 基本活动：
＆LT;活动
机器人：名字=。WrapperActivity
机器人：标签=@字符串/ APP_NAME
机器人：主题=@安卓风格/ Theme.NoDisplay/＆GT;
解决方案
这是全功能的，它是基于关闭在Android SDK ListView控件。这不是特别的小部件，但我敢肯定，使其适用于一个小部件，您可以修改它。
创建一个名为活动SearchActivity：
// CustomSearch（查看）及ISEARCH（接口）是我创建的对象和无关
公共类SearchActivity扩展AppCompatActivity实现ISEARCH
{
//变量
私人CustomSearch mSearchView;
@覆盖
公共无效的onCreate（捆绑savedInstanceState）
{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_search）; mSearchView =（CustomSearch）findViewById（R.id.search）;
mSearchView.setPendingComponentName（getComponentName（））;
mSearchView.setSearchListener（本）;
} @覆盖
保护无效onNewIntent（意向意图）
{
如果（Intent.ACTION_SEARCH.equals（intent.getAction（）））
{
查询字符串= intent.getStringExtra（SearchManager.QUERY）;
Log.i（搜索＆gt;中，你说：+查询）;
}
}
}
添加活动到的AndroidManifest.xml
＆LT;活动
机器人：名字=。activities.SearchActivity
机器人：标签=@字符串/ APP_NAME
机器人：主题=@风格/ CustomTheme.NoActionBar＆GT;
＆所述;意图滤光器＆gt;
＆lt;作用机器人：名字=android.intent.action.SEARCH/＆GT;
＆所述; /意图滤光器＆gt;
＆LT; /活性GT;
在自定义的Widget /视图：
buttonVoice.setOnClickListener（新View.OnClickListener（）
{
@覆盖
公共无效的onClick（视图v）
{
//无论从SearchableInfo或组件名获取活动
组件名searchActivity = mComponentName; 在意图//裹组件
意图queryIntent =新意图（Intent.ACTION_SEARCH）;
queryIntent.setComponent（searchActivity）; 在悬而未决的意图//包裹的查询意图
的PendingIntent未决= PendingIntent.getActivity（的getContext（），0，queryIntent，PendingIntent.FLAG_ONE_SHOT）; //现在创建包，因为如果我们在挂起的意图把它包起来，就成了不可改变
捆绑queryExtras =新包（）; //创建语音意图
意图voiceIntent =新意图（RecognizerIntent.ACTION_RECOGNIZER_SPEECH）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_LANGUAGE_MODEL，RecognizerIntent.ACTION_RECOGNIZE_SPEECH）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_PROMPT，说话）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_CALLING_PACKAGE，searchActivity
voiceIntent.addFlags（Intent.FLAG_ACTIVITY_NEW_TASK）; //裹挂起的意图和放大器;捆绑的声音里面的意图
voiceIntent.putExtra（RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT，待定）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT_BUNDLE，queryExtras）; //启动语音搜索
。的getContext（）startActivity（voiceIntent）;
}
}
Like in this question (accepted answer), I'm trying to launch voice recognition from one of my app's widgets. I succesfully managed to open dialog that requests voice input with this code inside onUpdate() method of the Widget:
// this intent points to activity that should handle results, doesn't work
Intent activityIntent = new Intent(SoulissApp.getAppContext(), WrapperActivity.class );
//doesn't work as well
//activityIntent.setComponent(new ComponentName("it.angelic.soulissclient", "it.angelic.soulissclient.WrapperActivity"));
// this intent wraps results activity intent
PendingIntent resultsPendingIntent = PendingIntent.getActivity(SoulissApp.getAppContext(), 0, activityIntent, 0);
// this intent calls the speech recognition
Intent voiceIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
voiceIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speech recognition demo");
voiceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT, resultsPendingIntent);
Bundle fakeBun = new Bundle();
fakeBun.putChar("fake", 'f');
voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT_BUNDLE, fakeBun);
// this intent wraps voice recognition intent, works
PendingIntent pendingInt = PendingIntent.getActivity(context, 0, voiceIntent, 0);
updateViews.setOnClickPendingIntent(R.id.button1, pendingInt);
The speech recognition works, but at the end of the recognition process, my resultsPendingIntent is not called. Why?
From sys log, I read this:
...I/ActivityManager﹕ START u0 {cmp=it.angelic.soulissclient/.SoulissWidgetVoice (has extras)} from uid 10152 on display 0......
while I'd expect something like:
...I/ActivityManager﹕ START u0 {cmp=it.angelic.soulissclient/.WrapperActivity(has extras)}...
because .WrapperActivity is pending Intent while SoulissWidgetVoice is the widget class. Note that WrapperActivity itself can be correctly launched from other activities and it's a Theme.NoDisplay basic activity:
<activity
android:name=".WrapperActivity"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoDisplay"/>
解决方案
This is fully functional, and it's based off the ListView in the Android SDK. It's not particularly for a widget, but I'm sure you can modify it so that it works for a widget.
Create an activity called SearchActivity:
// CustomSearch (View) & ISearch (Interface) are objects that I created and are irrelevant
public class SearchActivity extends AppCompatActivity implements ISearch
{
// Variables
private CustomSearch mSearchView;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
mSearchView = (CustomSearch)findViewById(R.id.search);
mSearchView.setPendingComponentName(getComponentName());
mSearchView.setSearchListener(this);
}
@Override
protected void onNewIntent(Intent intent)
{
if (Intent.ACTION_SEARCH.equals(intent.getAction()))
{
String query = intent.getStringExtra(SearchManager.QUERY);
Log.i("SEARCH >", "You said: " + query);
}
}
}
Add activity to the AndroidManifest.xml
<activity
android:name=".activities.SearchActivity"
android:label="@string/app_name"
android:theme="@style/CustomTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.SEARCH"/>
</intent-filter>
</activity>
In your custom Widget/View:
buttonVoice.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
// Get activity from either SearchableInfo or ComponentName
ComponentName searchActivity = mComponentName;
// Wrap component in intent
Intent queryIntent = new Intent(Intent.ACTION_SEARCH);
queryIntent.setComponent(searchActivity);
// Wrap query intent in pending intent
PendingIntent pending = PendingIntent.getActivity(getContext(), 0, queryIntent, PendingIntent.FLAG_ONE_SHOT);
// Create bundle now because if we wrap it in pending intent, it becomes immutable
Bundle queryExtras = new Bundle();
// Create voice intent
Intent voiceIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZER_SPEECH);
voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
voiceIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak");
voiceIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, searchActivity
voiceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Wrap the pending intent & bundle inside the voice intent
voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT, pending);
voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT_BUNDLE, queryExtras);
// Start the voice search
getContext().startActivity(voiceIntent);
}
}
