java - Fragment 中的 TableLayout

Question

我正在创建一个将动态创建 tableLayout 的 fragment ，但我遇到了问题，因为它没有显示。有人可以告诉我为什么它不显示吗？除表格外，部分标签可以显示。

这是我的xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_fragment_bp_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="top"
android:orientation="vertical" >

<TextView
        android:id="@+id/section_bp_label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

<TableLayout
    android:id="@+id/tableLayoutBloodPressure"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >


</TableLayout>

</LinearLayout>

这是我的 fragment 类——数据仅供测试

public class BloodPressureFragment extends Fragment {

public BloodPressureFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_bp_list, container,
            false);

    TextView txt = (TextView) rootView.findViewById(R.id.section_bp_label);
    txt.setText("Blood Pressure History Logs");

    TableLayout ll = (TableLayout) rootView
            .findViewById(R.id.tableLayoutBloodPressure);

    for (int i = 1; i < 10; i++) {
        TableRow tbrow = new TableRow(getActivity().getApplicationContext());
        tbrow.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.WRAP_CONTENT));

        TextView tv1 = new TextView(getActivity().getApplicationContext());
        tv1.setLayoutParams(new TableRow.LayoutParams(
                TableRow.LayoutParams.MATCH_PARENT,
                TableRow.LayoutParams.WRAP_CONTENT));
        tv1.setId(i);

        tv1.setText("Test id: " + i);
        tbrow.addView(tv1);

        ll.addView(tbrow, new TableLayout.LayoutParams(
                LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
    }

    return rootView;
}
}

我有同样的问题，我的解决方案是从 fragment View 中扩充行布局。

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
    v = inflater.inflate(R.layout.fragment_intro_a,container,false); // infalte normally
    Tablelayout mytable = (TableLayout) v.findViewById(R.id.mytable); // init table

    /* your stuff*/

    /* now fill table layout directly on fragment */
    TableRow row = new TableRow(getActivity()); // new row
    View table_row_view = v.inflate(getActivity(),R.layout.your_layout,row); // inflate from parent view;
    row.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
    TextView mytextview = (TextView)vvv.findViewById(R.id.yourtextview-in-yourlayout);
    mytable.addView(row, new TableLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
    /* TADAAN! rows is visible! */
