我正在研究单选按钮和复选框按钮。值 0 表示单选，1 表示复选框。根据这些值，我想将其显示在屏幕上。可能同时有单选框和复选框。
现在，我从数据库中获取的值为 0 和 1，它只是为所有属性设置单选按钮或复选框。它应该显示值 1 的复选框和值 0 的单选按钮。
这是代码:
if(multiSelect != null)
{
RadioButton radioButton = new RadioButton(mMain);
radioButton.setText(name_price);
radioButton.setId(i + 6);
radioButton.setTextSize(12);
radioButton.setTag(attributes.get(num));
radioButton.setGravity(Gravity.START | Gravity.CENTER_VERTICAL);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1)
{
radioButton.setTextAlignment(View.TEXT_ALIGNMENT_VIEW_START);
}
setTextFont(radioButton, "Museo_Slab.otf");
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT,
1f);
lp.setMargins(10, 10, 0, 10); // llp.setMargins(left, top, right, bottom);
radioButton.setLayoutParams(lp);
attr_layout[j].addView(radioButton);
num++;
radioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
try
{
ItemAttributes itemAttributes = (ItemAttributes) buttonView.getTag();
if (isChecked)
{
float total_price = current_price + attr_price;
item.setItemPrice(total_price + "");
item_price_text.setText(priceStr);
selectedAttributes.add(itemAttributes);
}
// If the attributes are not checked
} catch (Exception ex)
{
GSLogger.e(ex);
}
}
});
}
else // if the multiSelect is 1
{
CheckBox checkBox = new CheckBox(mMain);
checkBox.setText(name_price);
checkBox.setId(i + 6);
checkBox.setTextSize(12);
checkBox.setTag(attributes.get(num));
checkBox.setGravity(Gravity.START | Gravity.CENTER_VERTICAL);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1)
{
checkBox.setTextAlignment(View.TEXT_ALIGNMENT_VIEW_START);
}
setTextFont(checkBox, "Museo_Slab.otf");
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT,
1f);
lp.setMargins(10, 10, 0, 10); // llp.setMargins(left, top, right, bottom);
checkBox.setLayoutParams(lp);
attr_layout[j].addView(checkBox);
num++;
// Reads the value depending on attribute User Selects
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
try
{
ItemAttributes itemAttributes = (ItemAttributes) buttonView.getTag();
if (isChecked)
{
float total_price = current_price + attr_price;
item.setItemPrice(total_price + "");
item_price_text.setText(priceStr);
selectedAttributes.add(itemAttributes);
}
} catch (Exception ex)
{
GSLogger.e(ex);
}
}
});
}
}
}
}
根据定义的项目组，假设它是 0 或 1，它应该将其显示在屏幕上。如果该组有两个选项，则屏幕应显示 0 值的单选按钮和 1 值的复选框。
最佳答案
您的 if 条件仅允许添加其中一个。您应该检查该值是否为 0，然后添加单选按钮，如果值为 1，则应添加复选框。您已经实现了 if else block 而不是 2 个 if block 。
if(value == 0)
{
RadioButton radioButton = new RadioButton(mMain);
radioButton.setText(name_price);
radioButton.setId(i + 6);
radioButton.setTextSize(12);
radioButton.setTag(attributes.get(num));
radioButton.setGravity(Gravity.START | Gravity.CENTER_VERTICAL);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1)
{
radioButton.setTextAlignment(View.TEXT_ALIGNMENT_VIEW_START);
}
setTextFont(radioButton, "Museo_Slab.otf");
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT,
1f);
lp.setMargins(10, 10, 0, 10); // llp.setMargins(left, top, right, bottom);
radioButton.setLayoutParams(lp);
attr_layout[j].addView(radioButton);
num++;
radioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
try
{
ItemAttributes itemAttributes = (ItemAttributes) buttonView.getTag();
if (isChecked)
{
float total_price = current_price + attr_price;
item.setItemPrice(total_price + "");
item_price_text.setText(priceStr);
selectedAttributes.add(itemAttributes);
}
// If the attributes are not checked
} catch (Exception ex)
{
GSLogger.e(ex);
}
}
});
}
if(value==1)
{
CheckBox checkBox = new CheckBox(mMain);
checkBox.setText(name_price);
checkBox.setId(i + 6);
checkBox.setTextSize(12);
checkBox.setTag(attributes.get(num));
checkBox.setGravity(Gravity.START | Gravity.CENTER_VERTICAL);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1)
{
checkBox.setTextAlignment(View.TEXT_ALIGNMENT_VIEW_START);
}
setTextFont(checkBox, "Museo_Slab.otf");
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT,
1f);
lp.setMargins(10, 10, 0, 10); // llp.setMargins(left, top, right, bottom);
checkBox.setLayoutParams(lp);
attr_layout[j].addView(checkBox);
num++;
// Reads the value depending on attribute User Selects
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
try
{
ItemAttributes itemAttributes = (ItemAttributes) buttonView.getTag();
if (isChecked)
{
float total_price = current_price + attr_price;
item.setItemPrice(total_price + "");
item_price_text.setText(priceStr);
selectedAttributes.add(itemAttributes);
}
} catch (Exception ex)
{
GSLogger.e(ex);
}
}
});
}
