Android TableRow中以编程方式添加的元素的权重不'；行不通

因此，我有一个

TableLayout

，在一个xml文件中有4个

TableRow

。我还有一个xml文件，定义了一个

TextView

，它将插入到行中（每行3个

TextView

）。 我希望那些

TextView

具有相同的宽度，并且当所有内容都在同一个xml文件中时，它们工作得很好（在开始时，我的

TextView

是“硬编码的”），但现在我以编程方式添加它们，它们的宽度不一样了

这是第一个XML文件

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/homeTable"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/lmbg"
    android:clickable="true"
    android:padding="20dp" >

    <TableRow
        android:id="@+id/tableRow1"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:minHeight="200dp" >
    </TableRow>

    <TableRow
        android:id="@+id/tableRow2"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:minHeight="200dp" >
    </TableRow>

    <TableRow
        android:id="@+id/tableRow3"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:minHeight="200dp" >
    </TableRow>

    <TableRow
        android:id="@+id/tableRow4"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:minHeight="200dp" >
    </TableRow>

</TableLayout>

最后，这是我如何以编程方式添加它们的

for(int i = 0; i < mTopCategories.size(); i++){     
    Category c = mTopCategories.get(i);
    TableRow row = ((TableRow)findViewById(rowID[idIdx])) ;
    cat = (TextView) getLayoutInflater().inflate(R.layout.cat_grid_item, null);
    int iconID = getResources().getIdentifier(c.getSlug().replace('-', '_'), "drawable", getPackageName());
    cat.setCompoundDrawablesWithIntrinsicBounds(0, iconID, 0, 0);
    int textID = getResources().getIdentifier(c.getSlug().replace('-', '_'), "string", getPackageName());
    cat.setText(textID);
    cat.setTag(c.getId().toString());
    row.addView(cat);
    }

for（inti=0；i

尝试在文本视图上明确设置布局参数，如下所示：

TableRow.LayoutParams lParams = new TableRow.LayoutParams(0, -2 /* WRAP_CONTENT */, 0.33f /* 33% of width */);
cat.setLayoutParams(lParams);

尝试这种方式，您甚至不需要任何xml。
Try this way,you even no required any xml.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TableLayout table = new TableLayout(this);
        table.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.MATCH_PARENT));

        int id=1;
        for (int i=0;i<4;i++){
            TableRow tableRow = new TableRow(this);
            tableRow.setOrientation(TableLayout.HORIZONTAL);
            for(int j=0;j<3;j++){
                TextView textView = new TextView(this);
                textView.setGravity(Gravity.CENTER);
                textView.setId(id++);
                textView.setText(String.valueOf(textView.getId()));
                textView.setTag(textView.getId());
                textView.setTextColor(Color.WHITE);
                textView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Toast.makeText(context, "Id is : " + v.getId(), Toast.LENGTH_SHORT).show();
                    }
                });
                textView.setBackgroundColor(Color.BLUE);
                TableRow.LayoutParams textviewParams = new TableRow.LayoutParams(0, TableRow.LayoutParams.MATCH_PARENT,1f);
                textviewParams.setMargins(5, 5, 5, 5);
                tableRow.addView(textView,textviewParams);
            }
            table.addView(tableRow,new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT,0,1f));
        }
        setContentView(table);

    }

@凌驾
创建时受保护的void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
TableLayout table=新的TableLayout（本）；
table.setLayoutParams（新的TableLayout.LayoutParams（TableLayout.LayoutParams.MATCH_父项，TableLayout.LayoutParams.MATCH_父项））；
int-id=1；
对于（int i=0；i优秀的解决方案，但为了将来参考，您可以
TableRow.LayoutParams.WRAP_CONTENT
Try this way,you even no required any xml.
