我想创建一个会说话的头像，在Android中使用Android和drawable frame anmation。唇形同步图像存储在drawable文件夹中。这是按下发言按钮时执行的功能。
该功能的要点是，根据出现的字母，每个相应的唇形同步动作被添加到动画中。其余的动作基于所选择的语言，决定音高和语速。线程用于运行动画和语音并行。
b1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//thread to add the animation
Thread avatarSp = new Thread(new Runnable() {
@Override
public void run() {
String toSpeak = ed1.getText().toString();
String[] words = toSpeak.split(" ");
for (String word : words) {
word = word.toLowerCase();
char[] letters = word.toCharArray();
for (int i = 0; i < letters.length; i++) {
if (letters[i] == 'a') {
if (sr1 == 1)
avatarSpeak.addFrame(getResources().getDrawable(R.drawable.a_i), 500);
else if (sr1 == 2)
avatarSpeak.addFrame(getResources().getDrawable(R.drawable.a_i), 750);
} else if (letters[i] == 'e') {
if (letters[i + 1] == 'i' || letters[i + 1] == 'a' || letters[i + 1] == 'e') {
i++;
if (sr1 == 1)
avatarSpeak.addFrame(getResources().getDrawable(R.drawable.e), 500);

avatarSpeak.addFrame(getResources().getDrawable(R.drawable.e), 750);

Toast.makeText(getApplicationContext(), toSpeak, Toast.LENGTH_SHORT).show();
//speak
tts1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
tts1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null, null);
} else {
tts1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
}
}
});
}
整个编码测试的API级别是Android 5.0（21）和Android 6.0（AVD 23）。但当我按下发言按钮时，API会在AVD和手机上崩溃。你能告诉我：
1. Where the error could possibly be?
2. Is there a better way to do this and how?
如果它是新手，请耐心等待我，但我真的想知道更好的方法来实现功能，在我自己的代码中。

答案 0 :(得分：1)
您尝试从后台线程设置动画视图，但只有主线程可以触摸视图。摆脱线程，只需将代码放在主要的onClick方法中。
