java - 在 Android 中创建表格视图的问题

Question

我正在尝试编写一个变量表来显示来自 Android 数据库的数据。到目前为止，我可以显示 2 条不同的行，但程序不再创建任何行，我根本找不到错误。

主要活动：

package com.example.tabellentest;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Context;
import android.content.Intent;
import android.view.View;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    String[] textArray ={" Null "," Eins ", " Zwei ", " Drei ", " Vier ", " Fünf "," SechsHundertZweiUndDreizig ", " Sechs "};
    String[] textArray1 ={" 12Null "," 12Eins ", " 12Zwei ", " 12Drei ", " 12Vier ", " 12Fünf "," 12SechsHundertZweiUndDreizig ", " Sechs "};

    private TableLayout firstTable;
    private TableLayout secondTable;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ExpandTextView();
        this.firstTable = (TableLayout) findViewById(R.id.tableLayout1);
        this.secondTable = (TableLayout) findViewById(R.id.tableLayout2);

        ExpandTableRow();
    }
    public TextView CreateTextView(String text, int index){
        TextView textView1 = new TextView(getApplicationContext());
        textView1.setText(text);
        return textView1;
    }
    public void ExpandTextView (){
        LinearLayout linearLayout = findViewById(R.id.linearLayout1);
        for( int i = 0; i < textArray.length; i++ )
        {
            linearLayout.addView(CreateTextView(textArray[i], i));
            TextView textView = new TextView(this);
            //textView.setText(textArray[i]);
            //textView.setId(i);
            linearLayout.addView(textView);
        }
    }
    public void ExpandTableRow(){
        for (int ab = 2; ab < 8; ab++){
            LinearLayout linearLayout2 = findViewById(R.id.linearLayout2);
            for( int i = 0; i < textArray1.length; i++ ) {
                linearLayout2.addView(CreateTextView(textArray1[i], i));
            }
            Context context = getApplicationContext();
            TableRow row = new TableRow(context);
            secondTable.addView(row);
            for( int i = 0; i < textArray1.length; i++ ) {
            linearLayout2.addView(CreateTextView(textArray1[i], i));
            }
        }
  }
}

我希望任何人都可以给我一个提示以找到问题。
