我如何在 android studio 中仅通过一个按钮创建多个编辑文本

Question

我只想按一次按钮创建 N 个编辑文本。例如，我输入编辑文本的数量=20[在此处输入图像描述][1]，当我按下按钮时，在多个行和列中创建了所有 20 个编辑文本。

有什么解决办法吗？？

我的代码在下面

 String Type,number,tedad;
TextView pazireshnum;
EditText tedadbattri;
String id=ID;
private LinearLayout mLayout;
private EditText mEditText;
private ImageButton mButton;
int k = -1;
int flag,i;
int hint=1;
ArrayList<String> applnserverinstnos = new ArrayList<String>();
public static EditText textView[] = new EditText[100];
@SuppressLint("WrongViewCast")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_check_list);

    mLayout = (LinearLayout) findViewById(R.id.ln1);
   // mEditText = (EditText) findViewById(R.id.editText);
    mButton = (ImageButton) findViewById(R.id.imgbtn);
    tedadbattri=(EditText) findViewById(R.id.ed7);
    tedadbattri.setText("0");
    pazireshnum=(TextView)findViewById(R.id.tv4);
    tedad= tedadbattri.getText().toString();
    int Tedad = Integer.parseInt(tedad);
    mButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

                try {

                        k++;
                        flag = k;
                        final LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
                        lparams.setMargins(5, 10, 5, 10);
                        textView[flag] = new EditText(CheckList.this);
                        textView[flag].setLayoutParams(lparams);
                        textView[flag].setId(flag);
                        textView[flag].setPadding(5, 5, 5, 5);

                } catch (Exception e) {
                    e.printStackTrace();
                }

                    mLayout.addView(textView[flag]);
                    textView[flag].setHint("باتری"+hint);
                    hint++;
                    textView[flag].setId(hint);
                    textView[flag].setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);
                    textView[flag].setBackgroundResource(R.drawable.border4);
            }
    });

Answer 1

您可以使用 for 循环并在该循环中创建 EditText 并将它们添加到 FlowLayout 容器；也许 this implementation or ConstraintLayout's Flow

Answer 2

你可以检查一下这个程序，假设20可以分成4列5行。所以运行 for loop 在列和行上添加 editText 视图到 TableRow 和 TableLayout .

示例 main_activity.xml 使用 TableLayout 添加 EditText 。

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">


    <ImageButton
        android:id="@+id/imgbtn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        tools:layout_editor_absoluteX="137dp"
        tools:layout_editor_absoluteY="283dp" />
    <TableLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:id="@+id/table">
    </TableLayout>
</LinearLayout>

现在试试代码 -

   mButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            int total = 20;  // quantity of edit texts 20
            final int columns = 4;
            final int rows = total / columns;  // in this case rows would be 5


            TableLayout myTable = findViewById(R.id.table);

            //Params for TableRow and TableLayout
            final TableLayout.LayoutParams tableParams = new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.WRAP_CONTENT);
            final TableRow.LayoutParams rowParams = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT, 1);
           //apply to clear
            myTable.removeAllViews();
            for (int i = 0; i < rows; i++) {
                TableRow tableRows = new TableRow(getApplicationContext());


                for (int j = 0; j < columns; j++) {
                    EditText editText = new EditText(getApplicationContext());
                    editText.setText("voltage" + total--);
                    tableRows.addView(editText, rowParams);
                }
                myTable.addView(tableRows, tableParams);

            }
        }
    });
