Android TableLayout-在屏幕中央动态添加按钮

Question

请在下面的屏幕截图中查看平板电脑和手机上的不同结果。

activity.xml

<RelativeLayout
        android:id="@+id/firstLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:padding="0dp"
        android:layout_above="@+id/horizontal_divider"
        android:layout_below="@id/toolbar"
        android:gravity="center">

        <TableLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/tblLayout"
            android:gravity="center"
            android:padding="0dip"

        </TableLayout>
</RelativeLayout >

background_ic_btn_bonus.xml

对应的Java代码

    String[] iLayoutMap = getTableLayout();
    /*
    iLayoutMap contains split rows removing 2 
    2,0,0,0,0,0,0,2,0,0,0,0,0,0,2,0,0,1,1,1,0,2,0,0,0,1,0,0,2,0,0,0,0,0,0,2,0,0,0,0,0,0*/
    TableLayout tableLayout  = (TableLayout) findViewById(R.id.tblLayout);

    for(int i=1;i<iLayoutMap.length;i++){
        TableRow NewRow1 =new TableRow(this);
        NewRow1.setPadding(0, 0, 0, 0);
        NewRow1.setGravity(Gravity.CENTER);
        NewRow1.setHorizontalGravity(Gravity.CENTER);
        NewRow1.setVerticalGravity(Gravity.CENTER);

        String [] items = iLayoutMap[i].split("\\s*,\\s*");
        NewRow1.setWeightSum(items.length-1);
        for(int j = 0; j < items.length;j++) {
            if(items[j].equalsIgnoreCase("0")){


                Button btnAdd = new Button(context);
                btnAdd.setGravity(Gravity.CENTER);
                btnAdd.setTextSize(25);
                btnAdd.setTextColor(Color.WHITE);

                //btnAdd.setPadding(10   ,10,10,10);
                //btnAdd.setBackgroundResource(R.drawable.ic_btn_default);
                btnAdd.setBackgroundResource(R.drawable.background_ic_btn_default);
                btnAdd.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT ,1));
                NewRow1.addView(btnAdd);
            }else if(items[j].equalsIgnoreCase("1")){

                //https://stackoverflow.com/questions/3404582/adding-text-to-imageview-in-android



                Button btnAdd = new Button(context);
                String strId = Integer.toString(i) + Integer.toString(j-1);
                //btnAdd.setWidth(iObjectWidth);
                //btnAdd.setHeight(iObjectHeight);
                btnAdd.setId(Integer.valueOf(strId));
                btnAdd.setGravity(Gravity.CENTER);
                btnAdd.setTextSize(25);
                btnAdd.setTextColor(Color.WHITE);

                //btnAdd.setPadding(10   ,10,10,10);
                //btnAdd.setBackgroundResource(R.drawable.ic_btn_default);
                btnAdd.setBackgroundResource(R.drawable.background_ic_btn_bonus);
                btnAdd.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT,1 ));
                NewRow1.addView(btnAdd);
            }
        }
        NewRow1.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT,items.length-1));
        tableLayout.addView(NewRow1);
    }

功能

public String[] getTableLayout() {

    if (lvlinfo != null) {
        return lvlinfo.getLayout().split("2");
    }

    //Return this as default in case of failure
    String arr = "2,0,0,0,0,0,0,2,0,0,0,0,0,0,2,0,0,1,1,1,0,2,0,0,0,1,0,0,2,0,0,0,0,0,0,2,0,0,0,0,0,0";
    //String arr = "2,0,0,0,0,0,0,2,0,0,0,0,0,0,2,0,0,1,1,1,0,2,0,0,0,1,0,0,2,0,0,0,0,0,0,2,0,0,0,0,0,0";
    return arr.split("2");

}

预期结果（使用以下代码在Android 4.4.2平板电脑上正常工作）

实际结果（在操作系统> = 8.1.0的多部电话上进行测试）

尝试使用这样的填充：

<RelativeLayout
            android:id="@+id/firstLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:paddingLeft="someDp"   ->>>> Padding
            android:paddingRight="someDp" ->>>> Padding
            android:layout_above="@+id/horizontal_divider"
            android:layout_below="@id/toolbar"
            android:gravity="center">
    <TableLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/tblLayout"
                android:gravity="center"
                android:shrinkColumns="*"
                android:padding="0dip"
                android:layout_margin="0dip"
                android:layout_centerInParent="true"
                android:layout_centerHorizontal="true"
                android:layout_centerVertical="true"></TableLayout>
</RelativeLayout >
