无法启动TTS(文本到语音)
好的基本上我把一切都建立了,我已经建立了我的onClick方法很多次,但是这次它是建立在我的main.xml文件无法启动TTS(文本到语音)
<Button
android:layout_alignParentRight="true"
android:layout_height="40dip"
android:layout_width="80dip"
android:id="@+id/speak"
android:enabled="true"
android:visible="true"
android:text="Speak" >
</Button>
明显它有其他的东西来定义它的布局,但这是我的按钮内的xml布局之一,并且由于某种原因,每次我点击按钮时,它都会关闭整个应用程序,为什么? 也如果我设置它来添加一个onClickListener然后该按钮只是什么都不做。
我会成立我的onClick监听器这样
speak.setOnClickListener(this);
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.speak:
doSpeak();
break;
}
}
,它仍然不工作....所以我只是不知道我做错了什么
package com.write.it;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;

public class Speech extends Activity implements OnInitListener {
private EditText words = null;
private Button speakBtn = null;
private static final int REQ_TTS_STATUS_CHECK = 0;
private static final String TAG = "TTS Demo";
private TextToSpeech mTts = null;
private MediaPlayer player = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
words = (EditText)findViewById(R.id.wordsToSpeak);
speakBtn = (Button)findViewById(R.id.speak);
// Check to be sure that TTS exists and is okay to use
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, REQ_TTS_STATUS_CHECK);
}
public void doButton(View view) {
switch(view.getId()) {
case R.id.speak:
mTts.speak(words.getText().toString(), TextToSpeech.QUEUE_ADD, null);
break;
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQ_TTS_STATUS_CHECK) {
switch (resultCode) {
case TextToSpeech.Engine.CHECK_VOICE_DATA_PASS:
// TTS is up and running
mTts = new TextToSpeech(this, this);
Log.v(TAG, "Pico is installed okay");
break;
case TextToSpeech.Engine.CHECK_VOICE_DATA_BAD_DATA:
case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_DATA:
case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_VOLUME:
// missing data, install it
Log.v(TAG, "Need language stuff: " + resultCode);
Intent installIntent = new Intent();
installIntent.setAction(
TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
break;
case TextToSpeech.Engine.CHECK_VOICE_DATA_FAIL:
default:
Log.e(TAG, "Got a failure. TTS apparently not available");
}
}
else {
// Got something else
}
}
public void onInit(int status) {
// Now that the TTS engine is ready, we enable buttons
if(status == TextToSpeech.SUCCESS) {
speakBtn.setEnabled(true);
}
}
@Override
public void onPause()
{
super.onPause();
// if we're losing focus, stop playing
if(player != null) {
player.stop();
}
// if we're losing focus, stop talking
if(mTts != null)
mTts.stop();
}
@Override
public void onDestroy()
{
super.onDestroy();
if(player != null) {
player.release();
}
if(mTts != null) {
mTts.shutdown();
}
}
}
我的意思是我没有设置音量或设置或让它说话?我不告诉它做它应该做的事情?.....我的手机上的音量开启,媒体音量也开始上升,我有一个HTC evo 4G所以它应该工作..... 在这里我添加另一个话语和onClick方法

代码中有很多东西混淆在一起,特别是用StartActivityforResult()
检查引擎的部分。
请参阅工作TTS的这个例子:http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/TextToSpeechActivity.html
你也没有指派任何标识的按钮(?显然)莫非,另一个按钮使用ID?
/编辑: 首先,合并两个活动。如果您再次拨打onCreate()
,则会覆盖前一个。然后加入implements OnClickListener
与
speakBtn.setOnClickListener(this);
Eclipse会告诉你,你需要添加一个未实现的方法代替
speakBtn.setOnClickListener((OnClickListener) this);
。
如果你在你的问题上复制的XML代码是你必须声明,按钮,然后它缺少在处理你所期望的ID(R.id.speak)...
我建议你在doButton
函数中添加一些调试打印,看看在文本到语音转换等任何进一步之前,它是否被正确调用。
我刚刚在xml布局中取出了anroid:onClick方法 – 2012-01-08 22:22:27
没有另一个按钮没有使用ID,但我会看到我可以用StartActivityResult()做什么 – 2012-01-08 22:14:36
请发布布局xml,因为它看起来像有更多的一个按钮,我想这会有很大的帮助。 – Force 2012-01-08 22:17:10
我没有分配一个id其android:@ + id/speak – 2012-01-08 22:18:59
