我正在尝试将 aTableRow
分成 4 个相等的部分。第一个是 a TextView
,最后三个是RadioGroups
。我已经成功地将它们TableRow
分成了这些相等的部分。但是,每一行都是动态构建的,每行最多可能有 5RadioButtons
个RadioGroup
. 当在每个显示和功能中构建一个TableRow
5时,它们都被挤压在一起。发生这种情况时,有没有办法让多行,但仍然保持在同一部分的同一部分?当给定适当的参数时,基本上就像 a会变成多行?RadioButtons
RadioGroup
RadioButtons
RadioGroup
TableRow
TextView
本案例的 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);
XML 布局TableRow
正在被夸大:
