我有一个动态列表视图，单击列表项时，该字符串数组已转换为文本到语音功能，我将该字符串数组存储在字符串中，然后只有我将其转换为文本到语音。
我在这里包括了我的代码。
public class TTSList extends ListActivity implements TextToSpeech.OnInitListener {
private static final int ACTIVITY_CREATE=0;
private static final int ACTIVITY_EDIT=1;
private GinfyDbAdapter mDbHelper;
private SimpleCursorAdapter dataAdapter;
ListView lv;
public Button btnadd1;
private TextToSpeech tts;
String typed1;
public String praystring;
public TextView txtText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tts_list);
lv =(ListView)findViewById(R.id.list);
mDbHelper = new GinfyDbAdapter(this);
btnadd1 = (Button)findViewById(R.id.btnadd);
btnadd1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
createProject();
}
});
mDbHelper.open();
fillData();
registerForContextMenu(getListView());
}
@SuppressLint("NewApi")
@SuppressWarnings("deprecation")
private void fillData() {
mDbHelper.open();
Cursor projectsCursor = mDbHelper.fetchAllProjects1();
//startManagingCursor(projectsCursor);
// Create an array to specify the fields we want to display in the list (only TITLE)
String[] from = new String[]{GinfyDbAdapter.CATEGORY_COLUMN_PRAYERNAME,GinfyDbAdapter.CATEGORY_COLUMN_WDATE};
// and an array of the fields we want to bind those fields to (in this case just text1)
int[] to = new int[]{R.id.text1,R.id.date};
dataAdapter = new SimpleCursorAdapter(
this, R.layout.activity_row2,
projectsCursor,
from,
to,
0);
setListAdapter(dataAdapter);
EditText myFilter = (EditText) findViewById(R.id.myFilter);
myFilter.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {
}
public void onTextChanged(CharSequence s, int start,
int before, int count) {
dataAdapter.getFilter().filter(s.toString());
}
});
dataAdapter.setFilterQueryProvider(new FilterQueryProvider() {
public Cursor runQuery(CharSequence constraint) {
return mDbHelper.fetchProjectByName(constraint.toString());
}
});
tts = new TextToSpeech(this, this);
}
@Override

// Inflate the menu; this adds items to the action bar if it is present.
super.onCreateOptionsMenu(menu);
MenuInflater mi = getMenuInflater();
mi.inflate(R.menu.activity_main, menu);

@Override

Cursor Release = mDbHelper.fetchProject1(id);
String Releasename = Release.getString(Release.getColumnIndexOrThrow(GinfyDbAdapter.CATEGORY_COLUMN_GODNAME));

for (String temp : godname) {
for (String temp1 : prayfor) {
for (String temp2 : people) {
praystring = temp +" " + temp1 +" "+ temp2 + " ";
}
}
}
typed1 = praystring;
speakOut();
}
@Override
public void onDestroy() {
// Don't forget to shutdown tts!
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
int result = tts.setLanguage(Locale.US);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "This Language is not supported");
} else {
//btnaudioprayer.setEnabled(true);
speakOut();
}
} else {
Log.e("TTS", "Initilization Failed!");
}
}
private void speakOut() {
tts.speak(typed1, TextToSpeech.QUEUE_FLUSH, null);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
fillData();
}
在单击列表中的行时，它必须产生文本到语音的转换，但是现在我没有得到任何转换。
最佳答案
看起来您的tts尚未初始化。和你。
在onCreate中添加以下内容
tts = new TextToSpeech(getParent(),TTSList.this);
添加@Override注释
@Override
public void onInit(int status)
关于java - 在listitem点击中使用该功能时，文本到语音无法正常工作，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/18440636/
