Question

我试图将TableRow分成4个相等的部分。第一个是TextView，后三个是RadioGroups。我已成功将TableRow拆分为这些相等的部分。但是，每行都是动态构建的，每RadioButtons最多可能有RadioGroup行。在每个TableRow中构建RadioButtons并{5} RadioGroup时，所有内容都会显示和显示功能，但RadioButtons会被挤压在一起。有没有办法让RadioGroup在发生这种情况时有多行，但仍然保留在同一TableRow的相同部分？基本上，当给出适当的参数时，TextView会变成多线？

此案例的Java代码：

RadioButton rb1, rb2, rb3, rb4, rb5;
RadioGroup rg;
TextView tv;
TableLayout tl = (TableLayout) this.findviewById(R.string.tl);
LayoutInflater inflater = getLayoutInflater();

//set up TableRow and TextView
TableRow tr = (TableRow)inflater.inflate(R.layout.tablerow3q, tl, false);
tr.setBackgroundColor(Color.LTGRAY);
tv = (TextView)tr.findViewById(R.id.tv);
tv.setText("Some text");

//loop sets up 1 RadioGroup per increment, each with 5 RadioButtons
for(int i = 0; i < 3; i++) {
    rb1 = new RadioButton(this);
    rb2 = new RadioButton(this);
    rb3 = new RadioButton(this);
    rb4 = new RadioButton(this);
    rb5 = new RadioButton(this);

    rb1.setText("test1");
    rb2.setText("test2");
    rb3.setText("test3");
    rb4.setText("test4");
    rb5.setText("test5");

    //without these layouts, only four buttons are displayed, the other is cut off
    rb1.setLayoutParams(new RadioGroup.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f);
    rb2.setLayoutParams(new RadioGroup.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f);
    rb3.setLayoutParams(new RadioGroup.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f);
    rb4.setLayoutParams(new RadioGroup.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f);
    rb5.setLayoutParams(new RadioGroup.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f);

    //add RadioButtons to correct RadioGroup based on loop increment
    if(i == 0) {
        rg1 = (RadioGroup)tr.findViewById(R.id.rg1);
        rg1.addView(rb1);
        rg1.addView(rb2);
        rg1.addView(rb3);
        rg1.addView(rb4);
        rg1.addView(rb5);
    }
    if(i == 1) {
        rg1 = (RadioGroup)tr.findViewById(R.id.rg2);
        rg1.addView(rb1);
        rg1.addView(rb2);
        rg1.addView(rb3);
        rg1.addView(rb4);
        rg1.addView(rb5);
    }
    if(i == 2) {
        rg1 = (RadioGroup)tr.findViewById(R.id.rg3);
        rg1.addView(rb1);
        rg1.addView(rb2);
        rg1.addView(rb3);
        rg1.addView(rb4);
        rg1.addView(rb5);
    }
}
tl.addView(tr);

正在膨胀的TableRow的XML布局：

<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android">
    <TextView
        android:id="@+id/tv"
        android:layout_width="0dip"
        android:layout_height="fill_parent"
        android:layout_margin="1dip"
        android:layout_weight="0.25"
        android:background="#ffffff"/>
    <RadioGroup
        android:id="@+id/rg1"
        android:layout_width="0dip"
        android:orientation="horizontal"
        android:layout_margin="1dip"
        android:layout_weight="0.25"
        android:background="#ffffff"/>
    <RadioGroup
        android:id="@+id/rg2"
        android:layout_width="0dip"
        android:orientation="horizontal"
        android:layout_margin="1dip"
        android:layout_weight="0.25"
        android:background="#ffffff"/>
    <RadioGroup
        android:id="@+id/rg3"
        android:layout_width="0dip"
        android:orientation="horizontal"
        android:layout_margin="1dip"
        android:layout_weight="0.25"
        android:background="#ffffff"/>
</TableRow>

Answer 1

RadioGroup扩展了LinearLayout，它不包装其内容。但是，有几种方法可以解决这个问题：

复制RadioGroup类的源代码并对其进行修改以扩展其他类型的布局，例如TableLayout或RelativeLayout。您需要管理单选按钮的排列方式。
动态构建嵌套TableLayout并使用OnClickListener来处理选择/取消选择各种单选按钮。
