你必须使用表格布局。LayoutParams是这样的:

TextView tv = new TextView(v.getContext());
tv.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f));

最后一个参数是权重。

TextView txtview = new TextView(v.getContext());
LayoutParams params = new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
txtview.setLayoutParams(params);

1f表示weight=1;你可以给2f或3f，视图将根据空间移动

你也可以像这样单独给出权重，

LayoutParams lp1 = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);

 lp1.weight=1;

这应该对你有用

LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT LayoutParams.MATCH_PARENT);

param.weight=1.0f;

在那个布局中设置布局参数

创建参数变量

 android.widget.LinearLayout.LayoutParams params = new android.widget.LinearLayout.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, 1f);

1f是权重变量

设置您的小部件或布局

 TextView text = (TextView) findViewById(R.id.text);
 text.setLayoutParams(params);

TextView text = new TextView(v.getContext());
text.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                                                LayoutParams.WRAP_CONTENT, 1f));

(OR)

TextView tv = new TextView(v.getContext());
LayoutParams params = new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
tv.setLayoutParams(params);

1f表示weight=1;根据您的需要，您可以给出2f或3f，视图将根据空间移动。为了在线性布局中使视图之间的指定距离使用weightsum For“LinearLayout”。

LinearLayout ll_Outer= (LinearLayout ) view.findViewById(R.id.linearview);
LinearLayout llInner = new LinearLayout(this);
            LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FillParent, LinearLayout.LayoutParams.WrapContent);
            llInner.Orientation = Orientation.Horizontal;
            llInner.WeightSum = 2;
            ll_Outer.AddView(llInner);
