RadioGroup is very simple to use, but in general, it can only be arranged horizontally or vertically. It wouldn't be that simple if you arrange the multi-horizontal ones.
Maybe there is a child's shoes that should be said. Will it be possible to write RadioButton into LineLayout soon? After testing, I can do that, and at the beginning I did the same. However, I found a bug when I ran it - the radio button is no longer a single choice. And the selection event will not be heard. This requires us to find a way. In fact, it is not difficult to achieve. Just use a few more RadioGroups (to handle some events in the code).
On code:
Layout in:

This implements a multi-line layout, which is only part of my layout, where android:textSize=”@dimen/RB_text_size” defines the font size for myself.
Use and processing in:
public class SelectMoneyActivity extends BaseActivity {
String strBtnSelected = ""; //Record which option is selected
private RadioGroup rg1, rg2, rg3, rg4;
private RadioButton rb_1, rb_2, rb_3, rb_4, rb_5, rb_6, rb_7, rb_8, rb_9, rb_10;
@Override
protected void onCreate(Bundle savedInstanceState) {
(savedInstanceState);
setContentView(.activity_select_money);
initView();
}
private void initView() {
rg1 = (RadioGroup) findViewById(.radio1);
rg2 = (RadioGroup) findViewById(.radio2);
rg3 = (RadioGroup) findViewById(.radio3);
rg4 = (RadioGroup) findViewById(.radio4);
rb_1 = (RadioButton) findViewById(.rb_1);
rb_2 = (RadioButton) findViewById(.rb_2);
rb_3 = (RadioButton) findViewById(.rb_3);
rb_4 = (RadioButton) findViewById(.rb_4);
rb_5 = (RadioButton) findViewById(.rb_5);
rb_6 = (RadioButton) findViewById(.rb_6);
rb_7 = (RadioButton) findViewById(.rb_7);
rb_8 = (RadioButton) findViewById(.rb_8);
rb_9 = (RadioButton) findViewById(.rb_9);
rb_10 = (RadioButton) findViewById(.rb_10);
btn_back = (Button) findViewById(.btn_back);
btn_next = (Button) findViewById(.btn_next);
//Create a listener and register a listener for each RadioButton
BtnSelected btnSelected1 = new BtnSelected("1");
BtnSelected btnSelected2 = new BtnSelected("2");
BtnSelected btnSelected3 = new BtnSelected("3");
BtnSelected btnSelected4 = new BtnSelected("4");
BtnSelected btnSelected5 = new BtnSelected("5");
BtnSelected btnSelected6 = new BtnSelected("6");
BtnSelected btnSelected7 = new BtnSelected("7");
BtnSelected btnSelected8 = new BtnSelected("8");
BtnSelected btnSelected9 = new BtnSelected("9");
BtnSelected btnSelected10 = new BtnSelected("10");
rb_1.setOnClickListener(btnSelected1);
rb_2.setOnClickListener(btnSelected2);
rb_3.setOnClickListener(btnSelected3);
rb_4.setOnClickListener(btnSelected4);
rb_5.setOnClickListener(btnSelected5);
rb_6.setOnClickListener(btnSelected6);
rb_7.setOnClickListener(btnSelected7);
rb_8.setOnClickListener(btnSelected8);
rb_9.setOnClickListener(btnSelected9);
rb_10.setOnClickListener(btnSelected10);
//The listener of the click event public class BtnSelected implements {
private String btnId;
public BtnSelected(String str) {
btnId = str;
}
@Override
public void onClick(View v) {
strBtnSelected = btnId;//A selected item isSelect = true;
//Click on the first line and clear the click items of the other line if (("1") || ("2") || ("3")) {
();
();
();
} else if (("4") || ("5") || ("6")) {
();
();
();
} else if (("7") || ("8") || ("9")) {
();
();
();
} else {
();
();
();
}
}
}
}
It's done. Another way is to customize the RadioGroup implementation, but this is a bit complicated. I still came home from get off work.
Replenish:
Use (RadioButton's id) to initialize button A by default, but listening will not execute
solve:Because check=”true” has been set to button A in the layout; removing this property will perform monitoring.
The above is all the content of this article. I hope it will be helpful to everyone's study and I hope everyone will support me more.
