Question

目前我正在使用一个项目来垂直显示Android中的表格中的数据库值。我得到了横向的答案，现在我想要它是垂直的。

主要Activity.java

  public class MainActivity extends Activity {

String data = "";
TableLayout tl;
TableRow tr;

TextView label;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    tl = (TableLayout) findViewById(R.id.maintable);

    final GetDataFromDB getdb = new GetDataFromDB();
    new Thread(new Runnable() {
        public void run() {
            data = getdb.getDataFromDB();
            System.out.println(data);

            runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    ArrayList<Users> users = parseJSON(data);
                    addData(users);
                }
            });

        }
    }).start();
}

public ArrayList<Users> parseJSON(String result) {
    ArrayList<Users> users = new ArrayList<Users>();
    try {
        JSONObject jsono = new JSONObject(result);
        //JSONArray jArray = new JSONArray("users");

        JSONArray jArray = jsono.getJSONArray("agriculture1");
        for (int i = 0; i < jArray.length(); i++) {
            JSONObject json_data = jArray.getJSONObject(i);
            Users user = new Users();
            user.setId(json_data.getInt("id"));
            user.setCrop(json_data.getString("crop"));
            user.setCategory(json_data.getString("category"));
            user.setSoil_texture(json_data.getString("soil_texture"));
            users.add(user);
        }
    } catch (JSONException e) {
        Log.e("log_tag", "Error parsing data " + e.toString());
    }
    return users;
}

void addHeader(){

    label = new TextView(this);

    label.setPadding(30, 30, 30, 30);
    label.setBackgroundColor(Color.LTGRAY);
    LinearLayout Ll = new LinearLayout(this);
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(TableRow.LayoutParams.FILL_PARENT,

    params.setMargins(5, 5, 5, 5);
    //Ll.setPadding(10, 5, 5, 5);

    TextView soil = new TextView(this);
    soil.setText("Soil_Texture");
    soil.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,

activity_main.xml中

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

android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"

<ScrollView

    android:scrollbars="none"
    android:layout_below="@+id/textView1">

        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:stretchColumns="*"

Answer 1

你必须使用1张桌子吗？您可以拆分布局并使用两个表格，用于＆＃34;标题＆＃34;和价值观。

您可以像这样拆分布局：

<LinearLayout android:orientation="horizontal" android:layout_height="fill_parent" android:layout_width="fill_parent">
  <LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="0dp"/>
  <LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="0dp"/>
</LinearLayout>

然后在内部布局中添加表格。
