以编程方式设置TextView的布局权重

我正在尝试动态创建TableRow对象，并将它们添加到tableelayout。 TableRow对象有两个项，一个TextView和一个CheckBox。TextView项需要将其布局权重设置为1，以将CheckBox项推到最右边。

我找不到关于如何以编程方式设置TextView项的布局权重的文档。

当前回答

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);

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);

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

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);

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);
