在单选组中采用两个线性布局的单选按钮不起作用
Take Radio buttons in two linear layout in radio group not work
我想制作如下图。
我尝试使用线性布局进行设计,但它的网络在无线电组中。
在无线电组中只有两个方向垂直或水平所以我怎样才能做到这一点。
它应该在同一个广播组,因为它的选项是同一个问题。
提前致谢。
试试这个。

Java 代码:
private OnCheckedChangeListener listener1 = new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (checkedId != -1) {
m_group2.setOnCheckedChangeListener(null); // remove the listener before clearing so we don't throw that Whosebug exception(like Vladimir Volodin pointed out)
m_group2.clearCheck(); // clear the second RadioGroup!
m_group2.setOnCheckedChangeListener(listener2); //reset the listener
// Log.e("XXX2", "do the work");
int chkId1 = m_group1.getCheckedRadioButtonId();
int chkId2 = m_group2.getCheckedRadioButtonId();
int realCheck = chkId1 == -1 ? chkId2 : chkId1;
RadioButton rb = (RadioButton)findViewById(realCheck);
selected_mode = rb.getText().toString();
Log.i("Selected_Mode", "" + selected_mode);
}
}
};
private OnCheckedChangeListener listener2 = new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (checkedId != -1) {
m_group1.setOnCheckedChangeListener(null);
m_group1.clearCheck();
m_group1.setOnCheckedChangeListener(listener1);
//Log.e("XXX2", "do the work");
int chkId1 = m_group1.getCheckedRadioButtonId();
int chkId2 = m_group2.getCheckedRadioButtonId();
int realCheck = chkId1 == -1 ? chkId2 : chkId1;
RadioButton rb = (RadioButton)findViewById(realCheck);
selected_mode = rb.getText().toString();
Log.i("Selected_Mode", "" + selected_mode);
}
}
};
call the listener to OnCreate()
m_group1.setOnCheckedChangeListener(listener1);
m_group2.setOnCheckedChangeListener(listener2);
- 声明一个类型为 int "mCurrentId" 的字段,其中包含选中的 radioButton id
- 声明一个 int 数组来保存所有单选按钮 ID。
- 根据需要在 xml 中放置单选按钮,但给每个单选按钮一个 ID。
在YourActivity.onCreate中:
setUpRadioButtons();
在你的活动中:
//fields
int[] myRadioButtons;
int currentCheckedRadioButton = 0;
//setUpRadioButtons method
private void setUpRadioButtons() {
myRadioButtons= new int[6];
myRadioButtons[0] = R.id.first;
myRadioButtons[1] = R.id.second;
//..
for (int radioButtonID : myRadioButtons) {
findViewById(radioButtonID).setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View v) {
if (currentCheckedRadioButton != 0)
((RadioButton) findViewById(currentCheckedRadioButton)).setChecked(false);
currentCheckedRadioButton = v.getId();
}
});
}
}
