我正在尝试在Android上使用语音识别。下面是我的代码

这是负责启动语音识别的按钮的代码。 speak.setOnClickListener（新的OnClickListener（）{

下面是一个onActivityResult方法

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
        ArrayList<String> matches_Text = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
        Log.v("Results", matches_Text.get(0).toString());

//Update EditText cityname here

        String normalized_cityname = matches_Text.get(0).toString().trim();
        normalized_cityname = normalized_cityname.replace(" ","%20");
        try {
            getResponseString("http://api.openweathermap.org/data/2.5/weather?q="+normalized_cityname+"&units=metric", true);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (JSONException e) {

这就是你的意思吗

我认为文本有时是空的？！添加一个


if(matches_Text == null){
   Log.v("Results","matches_Text is NULL!"); 
   return;
}



在
ArrayList matches\u Text=da…
show getresponsestring method…添加完方法之后添加上述代码。因此打印字符串的log语句不会崩溃，但是如果在cityname.setText中使用相同的字符串，它会崩溃吗？字符串是否与您在日志中预期的一样？堆栈崩溃是什么？是否确定e您的cityname字段设置正确吗？是的，日志显示
结果：这是我一直说的
，然后崩溃说
虚拟机关闭了
。您能发布显示崩溃的日志吗？是的，我想这对我有帮助。
