Android自定义底部弹出框ButtomDialog

本文实例为大家分享了android自定义底部弹出框的具体代码，供大家参考，具体内容如下

先看看效果和你要的是否一样

一 、先来配置自定义控件需要的资源

1.在res文件夹下创建一个anim文件夹并创建两个slide_in_bottom.xml、slide_out_bottom.xml文件，负责弹框进出动画。

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
   android:shareinterpolator="false">
 <!-- slide_in_bottom.xml -->
 <translate
   android:duration="@integer/dp_300"
   android:fromxdelta="0%"
   android:toxdelta="0%"
   android:fromydelta="100%"
   android:toydelta="0%"/>
</set>

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
   android:shareinterpolator="false">
 <!-- slide_out_bottom.xml -->
 <translate
   android:duration="@integer/dp_300"
   android:fromxdelta="0%"
   android:toxdelta="0%"
   android:fromydelta="0%"
   android:toydelta="100%"/>
</set>

2.在style.xml添加阴影和动画样式。

 <style name="theme.light.notitle.dialog" parent="@android:style/theme.dialog">
    <item name="android:windowbackground">@android:color/transparent</item>
    <item name="android:windownotitle">true</item>
    <item name="android:windowisfloating">true</item>
    <item name="android:windowframe">@null</item>
  </style>
 
  <style name="theme.light.notitle.noshadow.dialog" parent="theme.light.notitle.dialog">
    <item name="android:backgrounddimenabled">false</item>
  </style>
 
  <style name="animation.bottom.rising" parent="@android:style/animation">
    <item name="android:windowenteranimation">@anim/slide_in_bottom</item>
    <item name="android:windowexitanimation">@anim/slide_out_bottom</item>
</style>

3.在drawable文件夹下创建一个title_background.xml文件，负责给文本内容添加背景。

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
  <corners android:radius="8dp"/>
  <solid android:color="#ffffffff"/>
</shape>

二、自定义控件的布局

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:orientation="vertical"
       android:padding="12dp"
       >
 
  <linearlayout
    android:background="@drawable/title_background"
    android:id="@+id/lay_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginbottom="8dp"
    android:orientation="vertical"/>
 
  <textview
    android:id="@+id/btn_cancel"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/title_background"
    android:paddingbottom="8dip"
    android:paddingtop="8dip"
    android:text="取消"
    android:gravity="center"
    android:textcolor="#007aff"
    android:textsize="17sp"/>
 
</linearlayout>

三、自定义控件类

public class buttomdialog extends dialog {
 
  public buttomdialog(context context, int themeresid) {
    super(context, themeresid);
  }
 
  public static class params {
    private final list<bottommenu> menulist = new arraylist<>();
    private view.onclicklistener cancellistener;
    private charsequence menutitle;
    private string canceltext;
    private context context;
  }
 
  public static class builder {
    private boolean cancancel = true;
    private boolean shadow = true;
    private final params p;
 
    public builder(context context) {
      p = new params();
      p.context = context;
    }
 
    public builder setcancancel(boolean cancancel) {
      this.cancancel = cancancel;
      return this;
    }
 
    public builder setshadow(boolean shadow) {
      this.shadow = shadow;
      return this;
    }
 
    public builder settitle(charsequence title) {
      this.p.menutitle = title;
      return this;
    }
 
    public builder addmenu(string text, view.onclicklistener listener) {
      bottommenu bm = new bottommenu(text, listener);
      this.p.menulist.add(bm);
      return this;
    }
 
    public builder addmenu(int textid, view.onclicklistener listener) {
      return addmenu(p.context.getstring(textid), listener);
    }
 
    public builder setcancellistener(view.onclicklistener cancellistener) {
      p.cancellistener = cancellistener;
      return this;
    }
 
    public builder setcanceltext(int resid) {
      p.canceltext = p.context.getstring(resid);
      return this;
    }
 
    public builder setcanceltext(string text) {
      p.canceltext = text;
      return this;
    }
 
    public buttomdialog create() {
      final buttomdialog dialog = new buttomdialog(p.context, shadow ? r.style.theme_light_notitle_dialog : r.style.theme_light_notitle_noshadow_dialog);
      window window = dialog.getwindow();
      window.setwindowanimations(r.style.animation_bottom_rising);
      window.getdecorview().setpadding(0, 0, 0, 0);
      windowmanager.layoutparams lp = window.getattributes();
      lp.width = windowmanager.layoutparams.match_parent;
      lp.height = windowmanager.layoutparams.wrap_content;
      window.setattributes(lp);
      window.setgravity(gravity.bottom);
      view view = layoutinflater.from(p.context).inflate(r.layout.dialog_bottom_menu, null);
      textview btncancel = (textview) view.findviewbyid(r.id.btn_cancel);
      viewgroup laycontainer = (viewgroup) view.findviewbyid(r.id.lay_container);
      viewgroup.layoutparams lpitem = new viewgroup.layoutparams(viewgroup.layoutparams.match_parent, viewgroup.layoutparams.wrap_content);
      viewgroup.marginlayoutparams lpdivider = new viewgroup.marginlayoutparams(viewgroup.layoutparams.match_parent, 1);
      lpdivider.setmargins(50,0,50,0);
      int dip1 = (int) (1 * p.context.getresources().getdisplaymetrics().density + 0.5f);
      int spacing = dip1 * 12;
      boolean hastitle = !textutils.isempty(p.menutitle);
      if (hastitle) {
        //标题样式
        textview ttitle = new textview(p.context);
        ttitle.setlayoutparams(lpitem);
        ttitle.setgravity(gravity.center);
        ttitle.settextcolor(p.context.getresources().getcolor(r.color.coloraccent));
        ttitle.settext(p.menutitle);
        ttitle.setpadding(0, spacing, 0, spacing);
        //单独给标题设置背景样式
//        ttitle.setbackgroundresource(r.drawable.common_dialog_selection_selector_top);
        laycontainer.addview(ttitle);
        view viewdivider = new view(p.context);
        viewdivider.setlayoutparams(lpdivider);
        viewdivider.setbackgroundcolor(0xffced2d6);
        laycontainer.addview(viewdivider);
      }
      //每一条的样式
      for (int i = 0; i < p.menulist.size(); i++) {
        bottommenu bottommenu = p.menulist.get(i);
        textview bbm = new textview(p.context);
        bbm.setlayoutparams(lpitem);
        bbm.setpadding(0, spacing, 0, spacing);
        bbm.setgravity(gravity.center);
        bbm.settext(bottommenu.funname);
        bbm.settextcolor(0xff007aff);
        bbm.settextsize(16);
        bbm.setonclicklistener(bottommenu.listener);
        laycontainer.addview(bbm);
        if (i != p.menulist.size() - 1) {
          view viewdivider = new view(p.context);
          viewdivider.setlayoutparams(lpdivider);
          viewdivider.setbackgroundcolor(0xffced2d6);
          laycontainer.addview(viewdivider);
        }
      }
 
      if (!textutils.isempty(p.canceltext)) {
        btncancel.settext(p.canceltext);
      }
 
      if (p.cancellistener != null) {
        btncancel.setonclicklistener(p.cancellistener);
      } else {
        btncancel.setonclicklistener(new view.onclicklistener() {
          @override
          public void onclick(view v) {
            dialog.dismiss();
          }
        });
      }
 
      dialog.setcontentview(view);
      dialog.setcanceledontouchoutside(cancancel);
      dialog.setcancelable(cancancel);
      return dialog;
    }
 
  }
 
  private static class bottommenu {
    public string funname;
    public view.onclicklistener listener;
 
    public bottommenu(string funname, view.onclicklistener listener) {
      this.funname = funname;
      this.listener = listener;
    }
  }
}

四、使用

public class mainactivity extends appcompatactivity implements view.onclicklistener {
 
  private button mdialogcustom;
  private buttommenudialog dialog;
 
  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.activity_main);
    initview();
  }
 
  private void initview() {
    mdialogcustom = (button) findviewbyid(r.id.custom_dialog);
    mdialogcustom.setonclicklistener(this);
  }
 
  @override
  public void onclick(view v) {
    switch (v.getid()) {
      case r.id.custom_dialog:
        buttommenudialog.builder builder = new buttommenudialog.builder(this);
        //添加条目，可多个
        builder.addmenu("相机", new view.onclicklistener() {
          @override
          public void onclick(view view) {
            dialog.cancel();
            toast.maketext(mainactivity.this, "相机", toast.length_short).show();
          }
        }).addmenu("相册", new view.onclicklistener() {
          @override
          public void onclick(view view) {
            dialog.cancel();
            toast.maketext(mainactivity.this, "相册", toast.length_short).show();
          }
        });
        //下面这些设置都可不写
        builder.settitle("这是标题");//添加标题
        builder.setcancancel(false);//点击阴影时是否取消dialog，true为取消
        builder.setshadow(true);//是否设置阴影背景，true为有阴影
        builder.setcanceltext("取消");//设置最下面取消的文本内容
        //设置点击取消时的事件
        builder.setcancellistener(new view.onclicklistener() {
          @override
          public void onclick(view view) {
            dialog.cancel();
            toast.maketext(mainactivity.this, "取消", toast.length_short).show();
          }
        });
        dialog = builder.create();
        dialog.show();
        break;
      default:
        break;
    }
  }
}
