disable checkbox after checked, android
提问by cgpa2.17
I want to achieve this : user check on a unchecked checkbox, a toast displayed, the checkbox then become disable..
我想实现这一点：用户选中未选中的复选框，显示吐司，然后复选框变为禁用..
male.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
// TODO Auto-generated method stub
if (isChecked){
Toast.makeText(CheckBoxTuts.this, "male" , Toast.LENGTH_SHORT).show();
male.setChecked(false);
}
}
});
the output failed, because they execute on the same time, even I put the male.setChecked(false) outside.. I can't recall there's something to run something 1st, then other thing.. is it thread? really cant remember
输出失败，因为它们同时执行，即使我把male.setChecked(false) 放在外面。真的不记得了

If you want to achieve: "user check on a unchecked checkbox, a toast displayed, the checkbox then become disable..",you should try this code:
如果您想实现：“用户检查未选中的复选框，显示吐司，然后复选框变为禁用..”，您应该尝试以下代码：
male.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
if (isChecked){
Toast.makeText(CheckBoxTuts.this, "male" , Toast.LENGTH_SHORT).show();
male.setEnabled(false); // disable checkbox
}
}
});

Try this....
尝试这个....
-Use the setEnabled(false)on the CheckBox
-使用setEnabled(false)上CheckBox
male.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
if (isChecked){
Toast.makeText(CheckBoxTuts.this, "male" , Toast.LENGTH_SHORT).show();
male.setEnabled(false); // Will Disable checkbox
}
}
});

Try to use .onClickListener(View.OnClickListener)with implemented View.OnClickListener. In body of implemented method you will check if the CheckBox is checked or not and set them.
尝试使用已.onClickListener(View.OnClickListener)实现的View.OnClickListener. 在实现的方法的主体中，您将检查 CheckBox 是否被选中并设置它们。

// TODO Auto-generated method stub
if (isChecked){
Toast.makeText(CheckBoxTuts.this, "male" , Toast.LENGTH_SHORT).show();
//male.setVisibility(View.GONE);//disappear your check box
male.setEnabled(false);//disable your check box
}
}
});

First , Register Your CheckBox to OnCheckedChangeListener.
首先，将 CheckBox 注册到 OnCheckedChangeListener。
chk.setOnCheckedChangeListener(this);
then, Overrides it's Method
然后，覆盖它的方法
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b)
{
if (chk.isChecked())
{
chk.setEnabled(false);
}
}
