百度语音助手集成到Fragment里面怎么避坑？

其实集成到Fragment才是比较实用的，但是没看到有相关详细的教程，所以本人尝试去挖这个坑看看能不能填上，终于终于还是搞出来了。
首先你还是要进行一些导包修改版本等相关的操作，不懂可以点下这个链接百度语音识别集成到HelloWorld，这个步骤完成后，回到你要集成的Fragment里面，可以看下我的Fragment的布局：

<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context=".VcFragment"> <RelativeLayout         android:layout_width="match_parent"         android:layout_height="match_parent"         tools:ignore="UselessParent"> <ImageView             android:id="@+id/iv_vc"             android:layout_width="100dp"             android:layout_height="100dp"             android:layout_alignParentEnd="true"             android:layout_alignParentBottom="true"             android:layout_marginEnd="154dp"             android:layout_marginBottom="160dp"             android:contentDescription="@string/to"             android:src="@drawable/ic_mkf" /> <TextView             android:id="@+id/tv_vcResult"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_alignParentTop="true"             android:layout_alignParentEnd="true"             android:layout_centerVertical="true"             android:layout_marginTop="163dp"             android:layout_marginEnd="0dp"             android:text="@string/ress"             android:textAlignment="center"             android:textColor="@color/colorPrimary"             android:textSize="20sp"             android:textStyle="bold" /> </RelativeLayout> </FrameLayout> 

逻辑代码如下：

if ("0".equals(error)) {                         resultTxt = msgObj.getString("best_result");                         tv_vcResult.setText(resultTxt); } } } catch (JSONException e) {                 e.printStackTrace(); } } } //释放资源 @Override public void onDestroy() { super.onDestroy(); if (myRecognizer != null) {             myRecognizer.release();//释放资源，不然程序会闪退             myRecognizer = null; } } //调用权限 private void initPermission() {         String[] permissions = {Manifest.permission.RECORD_AUDIO,                 Manifest.permission.ACCESS_NETWORK_STATE,                 Manifest.permission.INTERNET,                 Manifest.permission.READ_PHONE_STATE,                 Manifest.permission.WRITE_EXTERNAL_STORAGE,                 Manifest.permission.MODIFY_AUDIO_SETTINGS,                 Manifest.permission.ACCESS_WIFI_STATE,                 Manifest.permission.CHANGE_WIFI_STATE         };         ArrayList<String> toApplyList = new ArrayList<>(); for (String perm : permissions) { if (PackageManager.PERMISSION_GRANTED != ContextCompat.checkSelfPermission(Objects.requireNonNull(getActivity()), perm)) {                 toApplyList.add(perm);

} } @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { // 此处为android 6.0以上动态授权的回调，用户自行实现。 } 

然后你可以在自己的日志看到识别效果，但是你的TextView一点反应都没，怎么办呢？

首先把Android改成Project,找到以下路径

修改两行代码就可以了，如下图所示：
