如何开发像Talking Tom这样的语音识别应用程序？
1.我的要求是如何在没有按钮,触摸事件等任何事件的情况下识别语音
.2.所有录音样本都包含通过按钮,但我的要求是当用户在该时间讲话时识别语音并且当用户自动停止语音时用汤姆或鹦鹉
3 等其他声音修改声音.我已经通过按钮完成了

我的.java

File storageDir = new File(Environment.getExternalStorageDirectory(), "SRAVANTHI");
storageDir.mkdir();
Log.d(APP_TAG, "Storage directory set to " + storageDir);
outfile = File.createTempFile("hascode", ".3gp", storageDir);

// init recorder
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(outfile.getAbsolutePath());

// init player
player.setDataSource(outfile.getAbsolutePath());

try {
    recorder.prepare();
    recorder.start();
    recording = true;
} catch (IllegalStateException e) {
    Log.w(APP_TAG, "Invalid recorder state .. reset/release should have been called");
} catch (IOException e) {
    Log.w(APP_TAG, "Could not write to sd card");
}

recorder.stop();

用于播放按钮

try {
    playing = true; …

我正在开发Camera overly app,因为我正在使用相机api进行预览和叠加效果.我在某些手机中出现强制关闭错误,并且不会发生其他手机.

我的代码:

parameters = camera.getParameters(); 
List<Size> sizes = parameters.getSupportedPreviewSizes(); 
Size optimalSize = getOptimalPreviewSize(sizes, w, h); 
parameters.setPreviewSize(optimalSize.width, optimalSize.height);
parameters.setColorEffect(Camera.Parameters.EFFECT_SOLARIZE);
setCameraDisplayOrientation(MainActivity.this,0, camera); 
camera.getParameters(); 
camera.setParameters(parameters);

这些是我得到的调用堆栈

我正在开发摄影应用程序,为此我使用此代码:

Canvas canvas = new Canvas(bmOverlay);
TextPaint paint = new TextPaint();
paint.setColor(Color.RED);
paint.setTextAlign(Align.CENTER);
paint.setTextSize(50);
paint.setFlags(Paint.ANTI_ALIAS_FLAG);
// if the background image is defined in main.xml, omit this line
canvas.drawBitmap(mBitmap, 0, 0, null);
int left = measureTextWidth(paint, InstaTextActivity.CurrentWord);
int top = measureTextHeight(paint, InstaTextActivity.CurrentWord);

left = mBitmap.getWidth() / 2 - InstaTextActivity.textCount / 2;
top = mBitmap.getHeight() / 2 - InstaTextActivity.textCount / 2;
StaticLayout layout = new StaticLayout(InstaTextActivity.CurrentWord, paint, total,
 android.text.Layout.Alignment.ALIGN_NORMAL, (float) 1.0, (float) 0.0, true);
//canvas.save();
canvas.translate(left, top);
layout.draw(canvas);
//canvas.restore();

在这个代码我正在使用paint.setTextAlign(Align.CENTER).它与中心对齐,但文本不会从中心向左对齐,而是从中心向右对齐.另外,在画布上对齐文本的正确方法是什么？ …
