【问题描述】：

我正在尝试以编程方式对齐左侧单选按钮和右侧按钮的文本，而不是下一个屏幕截图中显示的内容

我尝试创建一个相对布局并放置 textview 和 radiobtn（不带文本），但每次尝试都失败 :(

我在这里发布了我尝试运行但无法对齐的代码。

        RelativeLayout relLay = new RelativeLayout(this);
        relLay.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

        TextView textView=new TextView(this);
        textView.setText(device.getName());
        textView.setGravity(Gravity.LEFT);  

        RadioButton radioBtn= new RadioButton(this);
        radioBtn.setText(" ");
        radioBtn.setTag(device);
        radioBtn.setChecked(false);
        radioBtn.setGravity(Gravity.RIGHT); 

        RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);

        lp1.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
        RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);

        lp2.addRule(RelativeLayout.ALIGN_PARENT_RIGHT,RelativeLayout.TRUE);

        relLay.addView(textView,lp1);
        relLay.addView(radioBtn,lp2);
        radioGr.addView(relLay);

我还必须指出，我正在将相对布局添加到由 ScrollView 包含的无线电组中。

提前感谢您的帮助和耐心

您可以使用以下代码：

RelativeLayout relLay = new RelativeLayout(this);
            relLay.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            relLay.setGravity(Gravity.RIGHT);
            TextView textView=new TextView(this);
            textView.setText("good");
            textView.setGravity(Gravity.RIGHT);  
            RadioButton radioBtn= new RadioButton(this);
            radioBtn.setChecked(false);
            radioBtn.setId(125); //you must setid for radioBtn

            RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);

          lp1.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
            RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(
                 RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
            lp1.addRule(RelativeLayout.ALIGN_BASELINE,radioBtn.getId());
          lp1.addRule(RelativeLayout.LEFT_OF,radioBtn.getId());
            lp2.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
            relLay.addView(radioBtn,lp2);
            relLay.addView(textView,lp1);
            this.setContentView(relLay);
