Android以编程方式将linearLayout添加到tableRow

Question

我正在以编程方式填充 tableLayout。我希望我的行是这样的

<TableRow android:id="@+id/tableRow1"
                        android:layout_width="wrap_content" android:layout_height="wrap_content">
                        <ImageView android:src="@drawable/icon" android:id="@+id/imageView1"
                            android:layout_height="wrap_content" android:layout_width="wrap_content"></ImageView>
                        <LinearLayout android:id="@+id/linearLayout2"
                            android:layout_width="wrap_content" android:layout_height="wrap_content"
                            android:orientation="vertical">
                            <TextView android:id="@+id/textView2" android:text="TextView"
                                android:layout_height="wrap_content" android:layout_width="wrap_content"></TextView>
                            <TextView android:text="TextView" android:id="@+id/textView1"
                                android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
                        </LinearLayout>
                        <Button android:text="Button" android:id="@+id/button1"
                            android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
                    </TableRow>

我已经通过这样做的代码尝试过

TableRow row = new TableRow(activity);
      row.setGravity(Gravity.CENTER);
      row.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT));


      image.setPadding(10, 10, 10, 10);       
      ((LinearLayout) image).setGravity(Gravity.LEFT);
      row.addView(image);

      LinearLayout main = new LinearLayout(row.getContext());
     main.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
      main.setOrientation(LinearLayout.VERTICAL);


      TextView nameView = new TextView(activity);

      if(name.length() > 22)
          nameView.setText(name.substring(0, 22)+"...");
      else
          nameView.setText(name);

      nameView.setPadding(10, 10, 10, 10);
      nameView.setTextColor(Color.parseColor("#83be56"));
      nameView.setTypeface(null,Typeface.BOLD);
      nameView.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));

      main.addView(nameView,new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));

      row.addView(main);

      bt.setText("Respond");
      bt.setPadding(10,10,10,10);
      bt.setGravity(Gravity.CENTER);

      row.addView(bt);

但是线性布局没有出现在行中。我哪里错了？？ 谢谢

Answer 1

您可以查看this SO answer，它解释了如何以编程方式创建TableRow，从部分XML 定义中扩展它。

编辑，在 cmets 之后：链接答案的要点是：

• 创建一个代表表格行的部分布局，并带有自己的样式集：

<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content"
  style="@style/tr_withborder" />

• 通过代码动态膨胀部分：

TableRow tr = (TableRow) getLayoutInflater().inflate(R.layout.partial_table_row, null);

Answer 2

以下是我以编程方式将 TableRows 添加到表格布局的方法。每个 View 问题实际上是一个 XML 文件，独立于它所在的 Fragment。该 Fragment 有一个 Tablelayout，questionContainer，它接收每个新问题并将其添加到底部（questionContainer 位于滚动视图中）：

public class EconFragment extends SherlockFragment {

private TableLayout questionContainer;
int pos = 0;
private String[] titles = {"The first title ", "hallo1","hallo2", "hallo3",
        "hallo4", "hallo5","hallo6", "hallo7","hallo8", "hallo9"};

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    Log.v("Econ", "onCreateView");
    View v = inflater.inflate(R.layout.econfragment, container, false);
    questionContainer = (TableLayout) v.findViewById(R.id.questionContainer);
    //bs
    int leftMargin=5;
    int topMargin=5;
    int rightMargin=5;
    int bottomMargin=5;
    while (pos < 10) {
    View question = inflater.inflate(R.layout.question, null);
    question.setId(pos);
    TextView title = (TextView) question.findViewById(R.id.questionTextView);
    title.setText(titles[pos]);
    Button charts = (Button) question.findViewById(R.id.chartsButton);
    charts.setId(pos);
    charts.setOnClickListener(chartsListener);
    TableRow tr = (TableRow) question;
    TableLayout.LayoutParams trParams = new TableLayout.LayoutParams(
            TableLayout.LayoutParams.MATCH_PARENT,
            TableLayout.LayoutParams.WRAP_CONTENT);
    trParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);
    tr.setLayoutParams(trParams);
    Log.v("econ", "while loop");
    questionContainer.addView(tr);
    pos++;
    }
    pos = 0;
    return v;
}

I would do something like this if I know the how many layouts i need to add.

    TableRow tableRow ;

    tableRow = findViewById(R.id.tableRow1);

    //Adding 2 LinearLayout 
    for (int i = 1; i <= 2; i++) {
        LinearLayout linearLayout= new LinearLayout (this);
        tableRow.addView(linearLayout);
    }
