帮助与Android的LinearLayout或RelativeLayout的 [英] Help with Android LinearLayout or RelativeLayout

问题描述

我需要以编程方式创建两个观点（因为我需要访问的美景之一的OnDraw）。出于某种原因，不管我做什么的意见添加到内容查看，他们不露面垂直堆叠，一是低于其他。

我可以把它就好使用使用RelativeLayout的布局定位的XML，但与XML，我不能创建一个视图对象，并重载OnDraw的方法做的。

我在做什么错误的方案办法，以及如何解决这个问题？

 的LinearLayout mLinearLayout;    公共无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;        //创建在其中添加ImageView的一个的LinearLayout
        mLinearLayout =新的LinearLayout（本）;        TextView的电视=新的TextView（本）;
            tv.setBackgroundColor（0xff333333）;
        tv.setText（请输入您的会员号：）;
        tv.setLayoutParams（新ViewGroup.LayoutParams（LayoutParams.FILL_PARENT，LayoutParams.WRAP_CONTENT））;        DrawableView I =新DrawableView（本）;
        i.layout（0,40,0,0）;
        i.setLayoutParams（新Gallery.LayoutParams（LayoutParams.WRAP_CONTENT，
                LayoutParams.WRAP_CONTENT））;        mLinearLayout.addView（电视）;
        mLinearLayout.addView（I，300,300）;
        的setContentView（mLinearLayout）;
    }
 

解决方案

您可以线性布局对象的方向设置为垂直

I need to create two views programmatically (because I need to access the ondraw of one of the views). For some reason, no matter what I do to add the views to the contentview, they don't show up vertically stacked, one below the other.

I can do it just fine using the XML using a RelativeLayout and layout positioning, but with the XML I can't create a view object and overload the ondraw method.

What am I doing wrong with the programmatic approach, and how do I solve this problem?

LinearLayout mLinearLayout;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Create a LinearLayout in which to add the ImageView
        mLinearLayout = new LinearLayout(this);

        TextView tv = new TextView(this);
            tv.setBackgroundColor(0xff333333);
        tv.setText("Enter your member number:");
        tv.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));



        DrawableView i = new DrawableView(this);
        i.layout(0,40,0,0);
        i.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));

        mLinearLayout.addView(tv);
        mLinearLayout.addView(i,300,300);
        setContentView(mLinearLayout);
    }

解决方案

you can set the orientation of the linear layout object to vertical
