android - .setText() 未附加到表 Android

Question

创建表后，不会填充行。我所拥有的只是列标题“fName”。fName.setText 似乎不起作用。我检查以确保completedWord.get(0)有一个值，并且确实如此。布局可能有问题，但我不确定。有什么建议么？

public void displayList () {
   int rowCount = completedWords.size();
   Log.d("Fill table", "rowCount = " + rowCount);
   TableLayout table = (TableLayout) this.findViewById(R.id.tablelayout);
   for (int i = 0; i <rowCount; i++) {
     fillRow(table, i);
   }
}

public void fillRow(TableLayout table, int noRow) {
    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View fullRow = inflater.inflate(R.layout.activity_main, null, false);
    TextView fName = (TextView) fullRow.findViewById(R.id.fName);
    System.out.println("Table should read " + completedWords.get(noRow));
    fName.setText(completedWords.get(noRow));
    fName.setId(noRow + 1);
    table.addView(fullRow);
}

XML 文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

不要膨胀R.layout.activity_main来获取 TextView 并添加到表中您可以动态创建 TextView 并将其添加到表中。

public void fillRow(TableLayout table, int noRow) {
TableRow fullRow = new TableRow(this);
TextView fName = new TextView(this);
System.out.println("Table should read " + completedWords.get(noRow));
fName.setText(completedWords.get(noRow));//or u can try completedWords.elementAt(noRow)
fName.setId(noRow + 1);
table.addView(fullRow);
}

Answer 2

尝试：

fName.setText(String.valueOf(completedWords.get(noRow)));

编辑：

我尝试了类似于你的代码的东西：

String[] words=new String[]{"this","is","an","example"};

public void displayList () {
           int rowCount = words.length;
           Log.d("Fill table", "rowCount = " + rowCount);
           TableLayout table = (TableLayout) this.findViewById(R.id.tablelayout);
           for (int i = 0; i <rowCount; i++) {
             fillRow(table, i);
           }
        }

        public void fillRow(TableLayout table, int noRow) {
            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View fullRow = inflater.inflate(R.layout.activity_main, null, false);
            TextView fName = (TextView) fullRow.findViewById(R.id.fName);
            //System.out.println("Table should read " + completedWords.get(noRow));
            fName.setText(String.valueOf(words[noRow]));
            //fName.setId(noRow);
            table.addView(fullRow);
        }

结果是这样的：

我认为你应该重新审视你的行布局。
