android - 访问动态文本字段值android

Question

我使用 foreach 循环创建了一些动态的 EditText 文件和一个按钮，代码如下:

void callDynamicView(){
        String configText="Building Name, S, 10; No: of Floors, I, 3; Area of Plot, D, 10; Location(X), L, 15.3;  Location(Y),  L, 15.3; Photo, P, 10";

        String[] splits = configText.split(";");
        ScrollView sv = new ScrollView(this);
        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.VERTICAL);
        sv.addView(ll);

        TextView tv = new TextView(this);
        tv.setText("Survey");
        tv.setTextColor(Color.rgb(200,0,0));
        ll.addView(tv);



        for(String splitSemi: splits){

            String[] splitsCommas = splitSemi.split(",");
            int len = splitsCommas[1].length();

            //Toast.makeText(getBaseContext(), len, Toast.LENGTH_SHORT).show();
            if(splitsCommas[1].equals("P")){
                Toast.makeText(getBaseContext(), "Keri", Toast.LENGTH_SHORT).show();
                Button btn = new Button(this);  
                btn.setText("Photo");
                ll.addView(btn);
                //this.setContentView(sv);
            }           
            else{

                //Toast.makeText(getBaseContext(), "else", Toast.LENGTH_SHORT).show();
                TextView txtv = new TextView(this);
                txtv.setText(splitsCommas[0]);
                ll.addView(txtv);

                EditText et = new EditText(this);
                ll.addView(et);

                }


        }

        Button btn = new Button(this);
        btn.setText("Submit");
        ll.addView(btn);
        this.setContentView(sv);

        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

        //  Toast.makeText(getBaseContext(), et.getText().toString(), Toast.LENGTH_SHORT).show();

            }
        });


    }

我想在单击按钮时访问所有输入的值。但是我无法获得这些值。我检查了各种可能性。我不熟悉动态创建 UI。可以帮助我吗？

按如下方式设置 EditText 的 ID...并将这些 ID 存储在 List 中以便稍后检索它们。

 List<Integer> editTextIdList = new ArrayList<Integer>();
 int id = 0;

 for(String splitSemi: splits){

        String[] splitsCommas = splitSemi.split(",");
        int len = splitsCommas[1].length();

        //Toast.makeText(getBaseContext(), len, Toast.LENGTH_SHORT).show();
        if(splitsCommas[1].equals("P")){

             .....
        }           
        else{

            //Toast.makeText(getBaseContext(), "else", Toast.LENGTH_SHORT).show();
            TextView txtv = new TextView(this);
            txtv.setText(splitsCommas[0]);
            ll.addView(txtv);

            EditText et = new EditText(this);
            et.seId(id);
            editTextIdList.add(id);
            ll.addView(et);

            id++;

        }
    }

在 OnClickListener 中...使用这些 ID 创建 EditText 实例并获取其文本如下...

   btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            for(int i = 0; i < editTextIdList.size(); i++) {

                EditText editText = (EditText)findViewById(editTextIdList.get(i));
                String text = editText.getText().toString();

            }

           // Toast.makeText(getBaseContext(), et.getText().toString(), Toast.LENGTH_SHORT).show();

        }
    });
