一、底部选择弹窗
效果：
1、自定义类
可自定义item数量的底部弹窗
（1）CustomBottomPop自定义类
package com.custom.jfrb.ui.first.customView; //自己的包位置
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;
import com.custom.jfrb.R;
import com.custom.jfrb.base.BasePopupWindow;
import com.custom.jfrb.ui.first.base.CustomPopListener;
import com.custom.jfrb.ui.first.bean.PopBean;
import org.droidparts.annotation.inject.InjectView;
import java.util.List;
/**
* 一个自定义item数量的底部弹出窗
*/
public class CustomBottomPop extends BasePopupWindow {
@InjectView(id = R.id.tv_cancel, click = true)
TextView tvCancel;
@InjectView(id = R.id.ll_root)
LinearLayout llRoot;
List<PopBean> data ;
CustomPopListener mMustomPopListener;
public CustomBottomPop(Context context, List<PopBean> list, CustomPopListener customPopListener) {
super(context);
this.data = list;
this.mMustomPopListener = customPopListener;
refresh();
}
public void refresh() {
clearItem();
for (PopBean bean : data) {
addItem(bean);
}
}
public void refresh(List<PopBean> list) {
this.data = list;
refresh();
}
Object object;
@Override
public View setPopview() {
return LayoutInflater.from(getContext()).inflate(R.layout.popup_bottom_custom, null);
}
public void clearItem() {
llRoot.removeAllViews();
}
private void addItem(final PopBean bean) {
View view = LayoutInflater.from(getContext()).inflate(R.layout.item_pop, null);
TextView textView = (TextView) view.findViewById(R.id.tv_button);
textView.setText(bean.getValue());
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mMustomPopListener.onClickButton(CustomBottomPop.this,bean);
}
});
llRoot.addView(view);
}
@Override
public void onClick(View v) {
if (v == tvCancel) {
dismiss();
}
}
public Object getObject() {
return this.object;
}
public void setObject(Object object) {
this.object = object;
}
}
（2）继承的BasePopupView类
package com.custom.jfrb.base;
import android.content.Context;
import android.graphics.drawable.BitmapDrawable;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.PopupWindow;
import com.custom.jfrb.R;
import org.droidparts.Injector;
import org.droidparts.bus.EventBus;
/**
* Created by Administrator on 2015/7/9 0009.
*/
public abstract class BasePopupWindow extends PopupWindow implements View.OnClickListener
{
public Context context;
public BasePopupWindow(Context context)
{
this.context = context;
onInit();
}
public Context getContext()
{
return this.context;
}
private void onInit()
{
setWidth(LinearLayout.LayoutParams.MATCH_PARENT);
setHeight(LinearLayout.LayoutParams.MATCH_PARENT);
View inflate = setPopview();
setContentView(inflate);
setBackgroundDrawable(new BitmapDrawable());
Injector.inject(getContentView(), this);
EventBus.unregisterAnnotatedReceiver(this);
EventBus.registerAnnotatedReceiver(this);
setAnimationStyle(R.style.PopupAnimation2);
}
protected BasePopupWindow()
{
}
public abstract View setPopview();
}
（3）R.layout.popup_bottom_custom
“取消”栏样式
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/rl_popup"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/half_transparent"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:background="@drawable/rnd_corner"
>
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<LinearLayout
android:id="@+id/ll_root"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
<View
android:layout_width="match_parent"
android:layout_height="@dimen/dk_dp_5"
android:background="#f2f2f2"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="45dp"
android:layout_alignParentBottom="true"
android:layout_marginBottom="10dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:gravity="center">
<TextView
android:id="@+id/tv_cancel"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="取消"
android:textColor="@color/black"
android:textSize="18dp"/>
</LinearLayout>
</LinearLayout>
</RelativeLayout>
（4）R.layout.item_pop
单个选择项样式，本文例子每个选项只展示一个TextView，整体可滑动
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/tv_button"
android:layout_width="match_parent"
android:layout_height="45dp"
android:layout_gravity="center"
android:gravity="center"
android:textColor="@color/black"
android:textSize="18dp"
tools:text="按钮1"/>
<TextView
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#eeeeee"/>
</LinearLayout>
</ScrollView>
</LinearLayout>
2、调用
（1）Activity类
public class PublishToShangguanActivity extends BaseActivity implements CustomPopListener {
//是否原创选择模块
@InjectView(id = R.id.ly_is_original,click = true)
private LinearLayout mLyOriginal;
//选择是否原创弹窗
CustomBottomPop originalSelectPop;
protected List<PopBean> originalLists = new ArrayList<>();
String[] originals = new String[]{"是","否"};
@Override
public void onPreInject() {
Utils.fitSystemWhite(this);
setContentView(R.layout.activity_publish_to_shangguan);
}
@Override
protected void onPostCreate() {
}
//重点关注监听这里，其余根据业务可变
@Override
public void onClick(View v) {
if (v == mLyOriginal){
//调出选择是否原创弹窗
originalLists.clear();
for (int i = 0;i < originals.length;i++){
originalLists.add(new PopBean(i,originals[i]));
}
originalSelectPop = new CustomBottomPop(this, originalLists, this);
originalSelectPop.setClippingEnabled(true);
originalSelectPop.showAtLocation(getRootView(), Gravity.CENTER, 0, 0);
}
}
//弹窗选择监听，可取出选择项的值
@Override
public void onClickButton(CustomBottomPop customBottomPop, PopBean bean) {
if (customBottomPop == originalSelectPop){
mTvOriginal.setText(bean.getValue());
}
customBottomPop.dismiss();
}
}
（2）自定义监听类 CustomPopListener.java
package com.custom.jfrb.ui.first.base;
import com.custom.jfrb.ui.first.bean.PopBean;
import com.custom.jfrb.ui.first.customView.CustomBottomPop;
/**
* Created by Administrator on 2018/3/1 0001.
*/
public interface CustomPopListener{
void onClickButton(CustomBottomPop customBottomPop, PopBean bean);
}
