如何将动态表格布局设置为特定布局的全屏显示？

Question

我正在尝试使用php来获取数据库，我已获取并以动态表布局显示，该行是根据数据库中的行数创建的，但是表布局位于屏幕的中心，但是我需要它以适合手机/标签页的整个屏幕。

我尝试更改特定屏幕上使用的所有布局的高度和宽度，但是没有任何改变可以帮助我解决此问题。

这是我的xml文件。

尝试为动态添加的每一行提供布局参数，并更新您的init()函数，如下所示：

@SuppressLint("ResourceType")
public void init() {
    TableLayout stk = (TableLayout) findViewById(R.id.table_main);
    TableRow tbrow0 = new TableRow(this);
    //added layout params and weight
    tbrow0.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
            TableRow.LayoutParams.WRAP_CONTENT, 1.0f));

    TextView tv0 = new TextView(this);
    tv0.setText(" Name ");//date
    tv0.setTextColor(Color.WHITE);
    //added layout params and weight
    tv0.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
            TableRow.LayoutParams.WRAP_CONTENT, 1.0f));
    tbrow0.addView(tv0);

    TextView tv1 = new TextView(this);
    tv1.setText(" Date ");//name
    tv1.setTextColor(Color.WHITE);
    //added layout params and weight
    tv1.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
            TableRow.LayoutParams.WRAP_CONTENT, 1.0f));
    tbrow0.addView(tv1);

    TextView tv2 = new TextView(this);
    tv2.setText(" Start Time ");//starttime
    tv2.setTextColor(Color.WHITE);
    //added layout params and weight
    tv2.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
            TableRow.LayoutParams.WRAP_CONTENT, 1.0f));
    tbrow0.addView(tv2);

    TextView tv3 = new TextView(this);

    tv3.setTextColor(Color.WHITE);
    //added layout params and weight
    tv3.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,

                    toast.show();
                }
            });

        }

    } catch (JSONException e) {
        e.printStackTrace();
    }
}

并通过 id = scrollView1 向android:fillViewport="true"提供ScrollView，并通过 id = hscrll1

提供HorizontalScrollView
