大家好， 我们想动态地在radiogroup旁边添加textview。基于服务响应，我们需要在不使用xml的情况下将标签添加到radiogroup。 在某些情况下基于最长无线电如何在android中动态添加textview到radiogroup
[
]
这里下面的代码
final RadioGroup rg = new RadioGroup(this); //create the RadioGroup
rg.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
rg.setOrientation(RadioGroup.VERTICAL);//or RadioGroup.VERTICAL
rg.setGravity(Gravity.CENTER);
final RadioButton[] rb = new RadioButton[items_list.size()];
final CheckBox[] cb = new CheckBox[items_list.size()];
for (int i = 0; i < items_list.size(); i++) {
LinearLayout ll_orientaion = new LinearLayout(this);
ll_orientaion.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT, 2.0f));
ll_orientaion.setOrientation(LinearLayout.HORIZONTAL);
ll_orientaion.setBackgroundColor(getResources().getColor(R.color.white));
ll_orientaion.setWeightSum(2);
ll_orientaion.setGravity(Gravity.CENTER);
if (max == 1) {
rb[i] = new RadioButton(this);
rb[i].setText(pd.getName());
rb[i].setGravity(Gravity.CENTER);
ll_orientaion.addView(rb[i]);
if (pd.getSelected_status().equals("true")) {
rb[i].setChecked(true);
}
hashMap_rdlist.put(rb[i].getText().toString(), rdd);
rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
ProductOptions rd_getlist = new ProductOptions();
int checkedRadioButtonId = rg.getCheckedRadioButtonId();
RadioButton radioButton = (RadioButton) findViewById(checkedRadioButtonId);
// Toast.makeText(ProductOptionsActivity.this, radioButton.getText(), Toast.LENGTH_SHORT).show();
String rd_name = (String) radioButton.getText();
});
} else {
cb[i] = new CheckBox(this);
cb[i].setButtonTintList(ColorStateList.valueOf(getColor(R.color.colorPrimary)));
cb[i].setText(pd.getName());
cb[i].setGravity(Gravity.CENTER);
ll_orientaion.addView(cb[i]);
}
final int finalI = i;
cb[i].setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
ProductOptions rd_getlist = new ProductOptions();
String check_name = (String) cb[finalI].getText();
if (isChecked) {
check_count++;
} else {
check_count--;
}
}
});
}
// Log.d("checklist",""+productoptions_skuId);
TextView tv = new TextView(this);
LinearLayout.LayoutParams tv1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1.0f);
tv.setLayoutParams(tv1);
tv1.weight = 2;
tv1.gravity = Gravity.CENTER;
tv.setText(pd.getSalePrice());
tv.setTextSize(14);
tv.setGravity(Gravity.END);
if (pd.getSalePrice().equals("0.0")) {
tv.setVisibility(View.INVISIBLE);
}
ll_orientaion.addView(tv);
rg.addView(ll_orientaion);
}
主要的问题，当我们添加的LinearLayout到radiGroup查看越来越完美，但单选按钮动作即不工作，
rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {}
请鬼谷de us 高级谢谢！

'RadioGroup'只能用于它自己的子节点，或者是RadioButton的子类。看来你正在将'LinearLayout'添加为'RadioGroup'子元素。 –
