java - android Listview onItemClick填充EditText

Question

我正在开发一个用于文本语音识别的小程序，问题是语音识别正在填充listView，这很好，现在我想用单击的ListView项目的内容填充EditText: 我的代码:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == VOICE_RECOGNITION_REQUEST_CODE)
        if(resultCode == RESULT_OK) {

            ArrayList<String> textMatchList = data
                    .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

            if (!textMatchList.isEmpty()) {
                mlvTextMatches.setAdapter(new ArrayAdapter<String>(this,
                                    android.R.layout.simple_list_item_1,
                                    textMatchList));


            }
        }

    mlvTextMatches.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id){
            //Not Sure what to do here!
            EditText InputText = (EditText) findViewById(R.id.inptWord);
        }
    });
    super.onActivityResult(requestCode, resultCode, data);
}`

有什么想法吗？

将 textMatchList 设为成员变量:

ArrayList<String> textMatchList = new ArrayList<String>();

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (requestCode == VOICE_RECOGNITION_REQUEST_CODE)
        if(resultCode == RESULT_OK) {
            textMatchList = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
    ...
    ...
    mlvTextMatches.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id){
            EditText InputText = (EditText) findViewById(R.id.inptWord);
            InputText.setText(textMatchList.get(position));
        }
    });
}

onItemClick 方法的 position 参数表示单击的列表项的位置。
