我如何使我的TableLayout适应不同类型的屏幕或Android版本？

问题描述 投票：0回答：1

我的活动中有一个TableLayout，它在Pixel API29（就像这样的https://ibb.co/T138m8G这样的ANdroi Pie）中可以很好地工作。

但是当我在较低的android版本（例如android 6.0）中尝试我的应用时，我的TableLayout会是这样。 https://ibb.co/ZK6VPcT

这是我的Java代码

FormReports.java

public class FormReports extends AppCompatActivity {

private Button btn, btnshare;
private LinearLayout llScroll;
private Bitmap bitmap;

@RequiresApi(api = Build.VERSION_CODES.KITKAT)
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_form_reports);
    btn = findViewById(R.id.btn);
    llScroll = findViewById(R.id.llScroll);
    btnshare = (Button) findViewById(R.id.btn_share);
    Toast.makeText(this, "Reports", Toast.LENGTH_SHORT).show();
    FormReports context = this;

    DatabaseHelper dataHelper = new DatabaseHelper(context);

    TableLayout tableLayout = (TableLayout) 
 findViewById(R.id.tablelayout);

    TableRow rowHeader = new TableRow(context);
    rowHeader.setBackgroundColor(Color.parseColor("#c0c0c0"));
    rowHeader.setLayoutParams(new 
 TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT,
            TableLayout.LayoutParams.MATCH_PARENT));
    String[] headerText = {"DATE", "COMPANY NAME", "DETAILS", "TIME IN", 
 "TIME OUT", "REMARKS"};
    for (String c : headerText) {
        TextView tv = new TextView(this);
        tv.setLayoutParams(new 
 TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
                TableRow.LayoutParams.MATCH_PARENT));
        tv.setGravity(Gravity.CENTER);
        tv.setTextSize(8);
        tv.setPadding(10, 10, 10, 10);
        tv.setText(c);
        tv.setTextColor(ContextCompat.getColor(context, R.color.black));
        rowHeader.addView(tv);
    }
    tableLayout.addView(rowHeader);

    // Get data from sqlite database and add them to the table
    // Open the database for reading
    SQLiteDatabase db = dataHelper.getReadableDatabase();
    // Start the transaction.
    db.beginTransaction();

    try {
        String selectQuery = "SELECT * FROM " + 
 DatabaseHelper.TABLE_NAME_OUT;
        Cursor cursor = db.rawQuery(selectQuery, null);

        if (cursor.getCount() > 0) {
            while (cursor.moveToNext()) {
                // Read columns data

                String out_td = 
 cursor.getString(cursor.getColumnIndex("timei_date"));
                String out_co = 
cursor.getString(cursor.getColumnIndex("timei_cu"));
                String out_st = 
cursor.getString(cursor.getColumnIndex("timei_st"));
                String out_in = 
cursor.getString(cursor.getColumnIndex("timei_in"));
                String out_out = 
cursor.getString(cursor.getColumnIndex("timei_out"));
                String out_le = 
cursor.getString(cursor.getColumnIndex("timei_legend"));

                // data rows
                TableRow row = new TableRow(context);
                row.setLayoutParams(new 
TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, 
TableLayout.LayoutParams.MATCH_PARENT));
                String[] colText = {out_td,
                                    out_co,
                                    out_st,
                                    out_in,
                                    out_out,
                                    out_le};

                for (String text : colText) {
                    TextView tv = new TextView(this);
                    tv.setLayoutParams(new

我只想使输出与我在任何尺寸的手机中显示给您的第一张图片相同，非常感谢。

只需像这样将您的layout_widths设置为match_parent：

<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">

<LinearLayout
    android:id="@+id/llScroll"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#fff"
    android:orientation="vertical">

<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">


<TableLayout
android:id= "@+id/tablelayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:shrinkColumns="0"
app:tabTextColor="@color/black">
