Android 带有ImageView和TextView的RelativeLayout-在ImageView下方对齐TextView，两者都以编程方式在RelativeLayout中居中

我与ImageView和TextView有一个相对论。我想在ImageView的正下方显示TextView（带有一个小的填充），同时显示ImageView和TextView，并在RelativeLayout中居中对齐

通过编程方式添加RelativeLayout

我已经阅读了一些关于对齐的问题，但是，我无法让它们为我工作。下面是我当前的代码

相对性代码

RelativeLayout relativeLayout = new RelativeLayout(this);

ImageView的代码

        ImageView image = new ImageView(this);  
        RelativeLayout.LayoutParams lpImage = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.WRAP_CONTENT,
                RelativeLayout.LayoutParams.WRAP_CONTENT);

        lpImage.addRule(RelativeLayout.CENTER_IN_PARENT);

        //Setting the parameters on the Image
        image.setLayoutParams(lpImage);

        //adding imageview to relative layout
        relativeLayout.addView(image);

TextView的代码

TextView textview = new TextView(this);
RelativeLayout.LayoutParams lpTextView = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            lpTextView.addRule(RelativeLayout.BELOW, image.getId());

            //Setting the parameters on the TextView
            textview.setLayoutParams(lpTextView);

            //Adding TextView to relative layout
            relativeLayout.addView(textview);

如果我为图像和文本在父视图中设置了

RelativeLayout.CENTER\u，它们会相互重叠，这是可以理解的，因为RelativeLayout支持视图重叠

我认为为textview设置
RelativeLayout.BELOW
会使其在图像下方对齐，但事实并非如此。我甚至尝试了textview的
RelativeLayout.ALIGN_BOTTOM
，但即使这样也没用。
试试这个

RelativeLayout relativeLayout = new RelativeLayout(this);

RelativeLayout.LayoutParams lprela = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT,
            RelativeLayout.LayoutParams.MATCH_PARENT);
relativeLayout.setLayoutParams(lprela);

ImageView image = new ImageView(this);  
    RelativeLayout.LayoutParams lpImage = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT);

    lpImage.addRule(RelativeLayout.ALIGN_PARENT_TOP);

    //Setting the parameters on the Image
    image.setLayoutParams(lpImage);

    //adding imageview to relative layout
    relativeLayout.addView(image);

    TextView textview = new TextView(this);
    RelativeLayout.LayoutParams lpTextView = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.WRAP_CONTENT,
                RelativeLayout.LayoutParams.WRAP_CONTENT);
        lpTextView.addRule(RelativeLayout.BELOW, image.getId());

        //Setting the parameters on the TextView
        textview.setLayoutParams(lpTextView);

        //Adding TextView to relative layout
        relativeLayout.addView(textview);

或

以下流程也可能适用于您。
1） 在垂直线性布局中添加图像视图和文本视图。
2） 将线性布局添加到相对布局的中心。（使用“父”中的“中心”）
我使用线性布局方法使其工作。谢谢你的回答。但是，有一个小小的变化。。使用、linearLayout.setGravity（Gravity.CENTER）代替layoutparams中的Gravity.CENTER，对我来说很有效。请相应地修改你的答案。谢谢回答已接受。@Hariharan感谢您分享您的代码，但我面临一个问题，当没有图像时，文本会移到中间。@Rstar只需删除
linearLayout.setGravity（Gravity.center）从父级
LinearLayout
并重试。
LinearLayout linearLayout = new LinearLayout(this);
LinearLayout.LayoutParams lp_ineer_ver = new LinearLayout.LayoutParams(
              LinearLayout.LayoutParams.MATCH_PARENT, 
              LinearLayout.LayoutParams.MATCH_PARENT);
linearLayout.setGravity(Gravity.CENTER);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setLayoutParams(lp_ineer_ver);

ImageView image = new ImageView(this);  
        LinearLayout.LayoutParams lpImage = new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.WRAP_CONTENT,
                LinearLayout.LayoutParams.WRAP_CONTENT);

        //Setting the parameters on the Image
        image.setLayoutParams(lpImage);

        //adding imageview to relative layout
        linearLayout.addView(image);

TextView textview = new TextView(this);
LinearLayout.LayoutParams lpTextView = new LinearLayout.LayoutParams(
                    LinearLayout.LayoutParams.WRAP_CONTENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT);

            //Setting the parameters on the TextView
            textview.setLayoutParams(lpTextView);

            //Adding TextView to relative layout
            linearLayout.addView(textview);
