嗨，我试图让代码通过我在 XML 中的数组列表，然后将它们放在表格布局中，但我无法从 XML 调用数组列表

我正在尝试这样的事情

ArrayList list = Collection(R.array.arraylist);
    int total = list.size();

for (int current = 0; current < total; current++)
    {
        // Create a TableRow and give it an ID
        TableRow tr = new TableRow(this);
        tr.setId(100+current);
        tr.setLayoutParams(new LayoutParams(
                LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));

 TextView labelTV = new TextView(this);
        labelTV.setId(200+current);
        labelTV.setText(list);
        labelTV.setTextSize(dip, 14);
        labelTV.setGravity(Gravity.CENTER);
        labelTV.setTextColor(Color.WHITE);
        labelTV.setLayoutParams(new LayoutParams(
                LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));
        tr.addView(labelTV);

我不认为它实际上是通过arraylist数据和textview不显示文本所以请帮助

使用 java 文件或 xml 文件创建表格布局

Step1：（Step 1有两种方式跟随任何一种）

/*create tablelayout in java no need for create activity that can be handle in java file if u want xml file use or condition loop*/

 TableLayout tableLayout=new TableLayout(this);
    tableLayout.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.MATCH_PARENT));
    setContentView(tableLayout);
/*Follow java code only then add the activity in manifest file then Go to step 2*/

  • --------------------或--------

    /在 xml 中创建 tablelayout 并在 java 中创建 getView /

XML:

<?xml version="1.0" encoding="utf-8"?>
  <TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/table"
         android:layout_width="match_parent"
         android:layout_height="match_parent">

 </TableLayout>

爪哇：

       setContentView(R.layout.table_layout);
 TableLayout tableLayout= (TableLayout) findViewById(R.id.table);

第2步：

    int colors[]=getResources().getIntArray(R.array.value);
    List<String> str=new ArrayList<String>();
    Collections.addAll(str, getResources().getStringArray(R.array.arrayvalues));
    Log.d(TAG,str.toString());
    for(int i=0;i<str.size();i++){
        TableRow row=new TableRow(this);
        row.setId(101+i);
        row.setBackgroundColor(Color.BLACK);
        row.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.MATCH_PARENT));

        TextView text=new TextView(this);
        text.setId(201+i);
        text.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT));
        text.setText(str.get(i));
        text.setPadding(0,10,0,10);
        text.setTextColor(colors[i]);


        row.addView(text);
        tableLayout.addView(row);
    }

字符串.xml

  <resources>
   <string-array name="arrayvalues">
    <item>Red</item>
    <item>Orange</item>
    <item>Yellow</item>
    <item>Green</item>
    <item>Blue</item>
    <item>Indigo</item>
    <item>Violet</item>
   </string-array>

   <integer-array name="value">
    <item>@color/Red</item>
    <item>@color/Orange</item>
    <item>@color/Yellow</item>
    <item>@color/Green</item>
    <item>@color/Blue</item>
    <item>@color/Indigo</item>
    <item>@color/Violet</item>
   </integer-array>
</resources>

颜色.xml

<resources>
<color name="Red">#FF0000</color>
<color name="Orange">#FF7F00</color>
<color name="Yellow">#FFFF00</color>
<color name="Green">#00FF00</color>
<color name="Blue">#0000FF</color>
<color name="Indigo">#4B0082</color>
<color name="Violet">#9400D3</color>
</resources>

输出：

仅用于从 string.xml 文件中获取数组（不要遵循它仅用于从字符串文件中获取数组）

    ArrayList<String> str=new ArrayList<String>();
    String[] val=getResources().getStringArray(R.array.value);
    str.addAll(Arrays.asList(val));
    Log.d(TAG,str.toString());

而不是labelTV.setText(list);你需要labelTV.setText(list.get(current));我猜

引用要用于设置文本的 ArrayList 的特定元素，大概是：

labelTV.setText(list.get(current)); // no idea what type you're dealing with, .toString() or a similar accessor may be necessary
