就是播放EditText中的内容

Acitivity中

import java.util.Locale;
import Android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class VoisePlayDemo extends Activity {
    private TextToSpeech mSpeech;
    private Button btn;
    private EditText mEditText;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        btn = (Button) findViewById(R.id.Button01);
        mEditText = (EditText) findViewById(R.id.EditText01);
        btn.setEnabled(false);
        //创建TextToSpeech对象
        mSpeech = new TextToSpeech(this, new OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    int result = mSpeech.setLanguage(Locale.US);
                    if (result == TextToSpeech.LANG_MISSING_DATA
                            || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                        Log.e("bb", "not use");
                    } else {
                        btn.setEnabled(true);
                    }
                }
            }
        });
        btn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                mSpeech.speak(mEditText.getText().toString(),
                        TextToSpeech.QUEUE_FLUSH, null);
            }
        });
    }
    @Override
    protected void onDestroy() {
        if (mSpeech != null) {
            mSpeech.stop();
            mSpeech.shutdown();
        }
        super.onDestroy();
    }
通过创建TextToSpeech类的实例并在 onInit 初始化方法内判断语音加载是否成功确实很简单了

就是不知道什么时候可以支持中文啊。
