Question

我正在从API中获取一些数据，并生成Android布局，但无法实现漂亮的布局，如下所示。

我希望TextView-> RadioGroup在TextView下面，以获取我收到的每个新数据。总是一个问题，一个广播小组。

这是我的代码：

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
//        setContentView(R.layout.activity_checklist);

        Intent intent = getIntent();
        int size = intent.getIntExtra("size", 0);
        Log.d(TAG, "onCreate - Qtd Questões: " + size);

        ScrollView scrollView= new ScrollView(this);
        RelativeLayout layout = new RelativeLayout(this);

        for (int i=0; i<size;i++) {

            RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(layoutParams);

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

            TextView tv1 = new TextView(this);
            tv1.setId(i+1);
            tv1.setText(intent.getStringExtra("q"+i));
            params1.addRule(RelativeLayout.BELOW, tv1.getId());

            // Initialize a new RadioGroup
            RadioGroup rg = new RadioGroup(getApplicationContext());
            rg.setOrientation(RadioGroup.HORIZONTAL);
            params2.addRule(RelativeLayout.BELOW, tv1.getId());
            rg.setId(i+1);

            // Create a Radio Button for RadioGroup
            RadioButton rb_sim = new RadioButton(getApplicationContext());
            rb_sim.setText("Sim");
            rb_sim.setId(i+i);
            rg.addView(rb_sim);

            RadioButton rb_nao = new RadioButton(getApplicationContext());
            rb_nao.setText("Não");
            rb_nao.setId(i+i);
            rg.addView(rb_nao);

            RadioButton rb_na = new RadioButton(getApplicationContext());
            rb_na.setText("Não se Aplica");
            rb_na.setId(i+i);
            rg.addView(rb_na);

            if (i > 0) {
                params1.addRule(RelativeLayout.BELOW, rg.getId());
                layout.addView(tv1,params1);
            } else {
                layout.addView(tv1);
            }
            layout.addView(rg, params2);
        }

        scrollView.addView(layout);
        setContentView(scrollView);
    }

可能我已经接近了，但是我看不出有什么问题。

尝试将“相对”布局更改为“线性”，然后检查输出。

RelativeLayout layout = new RelativeLayout(this);

收件人

LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);

希望这可以正常显示您的视图，而不会与textView重叠。

以编程方式生成的布局
