Question

我只想让TextView转入EditText的输入，但它不起作用。这也是一个自定义数组适配器，而不是Activity，如果这有任何区别。我也让它工作了，我改变了AndroidManifest.xml中的方向然后我将其更改回默认值，EditText输入不再更改TextView。

我甚至使用VCS本地历史回到我以前的代码我不知道发生了什么。这是我的代码。

class CustomAdapter extends ArrayAdapter{

    public CustomAdapter(Context context, ArrayList choreText) {
        super(context, R.layout.custon_listview_row, choreText);
    }

    @NonNull
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater myInflater = LayoutInflater.from(getContext());
        View customView = myInflater.inflate(R.layout.custon_listview_row, parent, false);
        ImageButton imageButton = (ImageButton) customView.findViewById(R.id.imageButton_ID);
        final TextView textView = (TextView) customView.findViewById(R.id.textView_ID);
        final EditText input = new EditText(getContext());
        final AlertDialog OptionDialog = new AlertDialog.Builder(getContext()).create();

        // makes textView clickable
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //what happens when textView is clicked

                //final AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
                // put aler dialog box logic here
                OptionDialog.setTitle("Enter new chore");
                OptionDialog.setView(input);
                input.setInputType(InputType.TYPE_CLASS_TEXT);
                input.setImeOptions(EditorInfo.IME_ACTION_DONE);
                //checks if "Done" button on soft keyboard is clicked
                input.setOnEditorActionListener(new TextView.OnEditorActionListener() {
                    @Override
                    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                        if(actionId==EditorInfo.IME_ACTION_DONE){
                            //what happens when "Done" is clicked
                            textView.setText(input.getText().toString());
                            OptionDialog.dismiss();

                        }
                        return false;
                    }
                });

                OptionDialog.show();
            }
        });

        imageButton.setImageResource(R.drawable.clock);

        return customView;
    }
}

编辑上面创建的文本oncreate并在onCreate（）

中编入索引

EditText editText;
onCreate()
 editText = (EditText) findViewById(R.id.edit_message);

//调用对话框并继续

 Button saveButton = (Button)dialog.findViewById(R.id.saveButton);
    saveButton.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            String text = ((EditText)dialog.findViewById(R.id.text)).getText().toString();
            editText.setText(text);
        }
    });

你可以在对话框中保留一个按钮，或者你可以继续自己的方式，但需要

如何从alertDialog将editText输入设置为textView
