公司有需求要做一个时间排版，原型例如以下
由于要用的gridView,曾经就是它的排版非常多，最看是想用一个checkbox搞定。
后来证实功能可以达到。可是排版是乱的。还是老老实实多写点吧（直接上代码）
技术不好什么地方不正确求指正
首先是主页：
public class MyActivity extends Activity {
/**
* Called when the activity is first created.
*/
private HashSet<Integer> shou = new HashSet<Integer>();
private int[] Mark = {1, 0, 1, 1, 1, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 1, 1, 0, 1, 0, 0, 0, 0, 0};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button) findViewById(R.id.button);
final WrapGridView wrapGridView = (WrapGridView) findViewById(R.id.gridview);
final DayTimeAdapter dayTimeAdapter = new DayTimeAdapter(this, Mark);
wrapGridView.setAdapter(dayTimeAdapter);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(MyActivity.this, "fdsgs", Toast.LENGTH_SHORT).show();
shou = dayTimeAdapter.remark();
Iterator<Integer> iterator = shou.iterator();
while (iterator.hasNext()) {
Log.i("mark", iterator.next() + "");
}
}
});
}
}
主要是 用来传入表示数组 和接受返回选中标识的
自己定义gridView：
public class WrapGridView extends GridView{
public WrapGridView(Context context) {
super(context);
}
public WrapGridView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public WrapGridView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int expandSpec=MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE>>2,MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
if (ev.getAction()==MotionEvent.ACTION_MOVE){
return true;//禁止滑动
}
return super.dispatchTouchEvent(ev);
}
}
这里是来来禁止滑动 只是onMeasure方法 只是你后面要在代码里自己设置高宽的时候须要
最后是适配器：
public class DayTimeAdapter extends BaseAdapter{
private ArrayList<Integer> Mark = new ArrayList<Integer>();
private String[] Time = {"8:00", "8:30", "9:00", "9:30", "10:00", "10:30", "11:00", "11:30", "12:00", "12:30", "13:00", "13:30", "14:00", "14:30",
"15:00", "15:30", "16:00", "16:30", "17:00", "17:30", "18:00", "18:30", "19:00", "19:30", "20:00"};
private LayoutInflater mInflater;
private HashSet<Integer> returnMark = new HashSet<Integer>();
public DayTimeAdapter(Context context, int[] m) {
mInflater = LayoutInflater.from(context);
for (int i = 0; i < m.length; i++) {
Mark.add(m[i]);
}
}
@Override
public int getCount() {
return Mark.size();
}
@Override
public Object getItem(int i) {
return Mark.get(i);
}
@Override
public long getItemId(int i) {
return i;
}
@Override
public View getView(final int i, View view, ViewGroup viewGroup) {
DayTimeHolder dayTimeHolder=null;
if (view == null||view.getTag()==null) {
view = mInflater.inflate(R.layout.item_time, null);
dayTimeHolder=new DayTimeHolder();
dayTimeHolder.checkBox = (CheckBox) view.findViewById(R.id.checkBox);
dayTimeHolder.timeName= (TextView) view.findViewById(R.id.textView);
view.setTag(dayTimeHolder);
}else {
dayTimeHolder = (DayTimeHolder) view.getTag();
}
dayTimeHolder.timeName.setText(Time[i]);
int a = Mark.get(i);
if (a == 0) {
view.setBackgroundColor(Color.parseColor("#04385A"));
dayTimeHolder.checkBox.setVisibility(View.INVISIBLE);
dayTimeHolder.checkBox.setClickable(false);
}
final View finalView = view;
final Handler handler = new Handler() {
public void handleMessage(Message msg) {
if (msg.what == 1) {
finalView.setBackgroundColor(Color.parseColor("#F0AB4E"));
// Log.i("mark","shoushoushou");
} else {
finalView.setBackgroundColor(Color.parseColor("#000000"));
}
}
};
dayTimeHolder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
Message msg = new Message();
if (b) {
msg.what = 1;
Log.i("mark", "111111111111");
returnMark.add(i);
} else {
msg.what = 2;
Log.i("mark", "22222222222222");
returnMark.remove(i);
}
handler.sendMessage(msg);
}
});
return view;
}
public HashSet remark() {
return returnMark;
}
}
class DayTimeHolder{
public CheckBox checkBox;//多选button
public TextView timeName;//时间名称
}
这里就是 直接初始化gridview结构。
里面用到的handler和message是动态更新选中状态的须要啦。
好久没写过这些了，我们这行除了技术就是经验了积累。
唉。怎么越学感觉自己越懒。。
