Question

在我的项目中，我在运行时生成了一些EDITTEXT，EDITTEXT的数量是可变的。必须恢复键入的文本并存储在不同的变量中，然后用它创建一个JSON对象。

以下是我用来创建EditText的方法：

public View editText(String nmLabel, String tpRender) {
    EditText e = new EditText(getBaseContext());
    e.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
    // e.setHint("DATE");

    if(tpRender.equals("NUMBER")) {
        e.setHint("NUMBER");
    }
    else if(tpRender.equals("DATE")) {
        e.setHint("DATE");
    }
    else if(tpRender.equals("TEXT")) {
        e.setHint("TEXT");
    }
    e.setTextColor(Color.BLACK);
    e.setTextSize(20);

    return(e);
}

如何单独输入文字？

由于您的EditTexts是在运行时创建的，并且您需要从所有这些中获取值来创建您的json，您可以使用List并在那里存储您的各个EditTexts。类似的东西：

在xml文件中：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    android:id="@+id/layout">

</LinearLayout>

在您的活动中，

    List<EditText> allEditTexts; // The List to hold all EditTexts
    LinearLayout layout; // The anchor layout

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        layout = (LinearLayout) findViewById(R.id.layout);
        allEditTexts = new ArrayList<EditText>();

        // I am running it three times, you can run as many times as you want

        for (int i = 0; i < 3; i++) {
        EditText editText = (EditText) editText("ANY LABEL", "NUMBER");
        layout.addView(editText);
        allEditTexts.add(editText);
        }

        // Now I am adding a button that will read the values from the List when clicked

        Button button = new Button(getApplicationContext());
        button.setText("Click");
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                // Read the input here for all EditTexts. Then you can store it in some Array or process it differently. In my code I have just logged them.

                for (EditText editText : allEditTexts) {
                    Log.d("TEXTINPUT", editText.getText().toString());
                }
            }
        });
        layout.addView(button);
    }

    // This is the code that you have, almost untouched.
    public View editText(String nmLabel, String tpRender) {
        EditText e = new EditText(getBaseContext());
        e.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
        // e.setHint("DATE");

        if (tpRender.equals("NUMBER")) {
            e.setHint("NUMBER");
        } else if (tpRender.equals("DATE")) {
            e.setHint("DATE");
        } else if (tpRender.equals("TEXT")) {
            e.setHint("TEXT");
        }
        e.setTextColor(Color.BLACK);
        e.setTextSize(20);
        allEditTexts.add(e);
        return (e);
    }

希望这能帮到你！
