最近要做个动态添加N个重复布局的功能、这种做法也是看了别的大神的博客、做下记录
外层布局文件
<LinearLayout
android:id="@+id/layout_implement"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView

android:paddingLeft="@dimen/qb_px_15"
android:paddingRight="@dimen/qb_px_15"
android:paddingTop="@dimen/qb_px_8"

<View style="@style/line" />
<LinearLayout

<View style="@style/line" />
</LinearLayout>
代码中：
//动态添加相同布局所需
private List<View> viewList = new ArrayList<>();
private List<ViewHolder> viewHolderList = new ArrayList<>();
private int mark = 0;
初始化第一次添加的布局：
/**
* 动态添加我、执行的
*/
private void initFirstView() {
View addView = LayoutInflater.from(ChangePointDetailPTRActivity.this).inflate(R.layout.item_add_change_ptr, null);
addView.setId(mark);
layoutAdd.addView(addView, mark);
getViewInstance(addView, mark);
}
public class ViewHolder {
private TextView tvPosition, tvPeopleDuty, tvDatePlan;
private EditText etImplement;
}
private void getViewInstance(View addView, int mark) {
ViewHolder viewHolder = new ViewHolder();
viewHolder.tvPosition = (TextView) addView.findViewById(R.id.tv_position);
viewHolder.etImplement = (EditText) addView.findViewById(R.id.et_implement);
viewHolder.tvPeopleDuty = (TextView) addView.findViewById(R.id.tv_people_duty);
viewHolder.tvDatePlan = (TextView) addView.findViewById(R.id.tv_date_plan);
viewHolderList.add(viewHolder);
viewList.add(addView);
// 设置监听
viewHolder.tvPeopleDuty.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
viewHolder.tvDatePlan.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Utils.showDateTimePicker(ChangePointDetailPTRActivity.this, viewHolder.tvDatePlan, true);
}
});
viewHolder.tvPosition.setText("序号：" + (mark + 1));
}
点击再次添加按钮：
/**
* 添加布局
*/
private void addViewAgain() {
mark++;
Log.e("布局位置", mark + "");
View addView = LayoutInflater.from(ChangePointDetailPTRActivity.this).inflate(R.layout.item_add_change_ptr, null);
addView.setId(mark);
layoutAdd.addView(addView, mark);
getViewInstance(addView, mark);
}
获取动态布局输入的内容：
private List<String> listTask = new ArrayList<>();
private List<String> listPeopleDuty = new ArrayList<>();
private List<String> listDatePlan = new ArrayList<>();
private void saveListData() {
for (int i = 0; i < layoutAdd.getChildCount(); i++) {
ViewHolder vh = viewHolderList.get(i);
listTask.add(vh.etImplement.getText().toString().trim());
listPeopleDuty.add(vh.tvPeopleDuty.getText().toString().trim());
listDatePlan.add(vh.tvDatePlan.getText().toString().trim());
}
}
