答案是您必须使用TableRow。LayoutParams，不是LinearLayout。LayoutParams或任何其他LayoutParams。

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

不同的LayoutParams是不可互换的，如果你使用了错误的LayoutParams，那么似乎什么都不会发生。文本视图的父视图是一个表行，因此:

还有另一种方法。如果你只需要设置一个参数，例如'height':

TextView textView = (TextView)findViewById(R.id.text_view);
ViewGroup.LayoutParams params = textView.getLayoutParams();
params.height = ViewGroup.LayoutParams.WRAP_CONTENT;
textView.setLayoutParams(params);

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);

这对我有用，我希望对你也有用

首先为父视图设置LayoutParams:

myTableLayout.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT,
                TableLayout.LayoutParams.FILL_PARENT));

然后为TextView(子)设置:

 TableLayout.LayoutParams textViewParam = new TableLayout.LayoutParams
     (TableLayout.LayoutParams.WRAP_CONTENT,
     TableLayout.LayoutParams.WRAP_CONTENT,1f);
     //-- set components margins
     textViewParam.setMargins(5, 0, 5,0);
     myTextView.setLayoutParams(textViewParam); 

答案是您必须使用TableRow。LayoutParams，不是LinearLayout。LayoutParams或任何其他LayoutParams。

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

不同的LayoutParams是不可互换的，如果你使用了错误的LayoutParams，那么似乎什么都不会发生。文本视图的父视图是一个表行，因此:

http://developer.android.com/reference/android/widget/TableRow.LayoutParams.html

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);
