环境:
- 主机:win10
- 开发环境:android studio 2.2 preview 3
说明:
两种方法实现底部弹出的对话框:
- dialog
- dialogfragment
推荐用dialogfragment
效果图:
布局文件dialog_select_call.xml:
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <relativelayout android:id="@+id/layout_voice" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/white"> <textview android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentstart="true" android:layout_centerinparent="true" android:textsize="16sp" android:textcolor="@color/black" android:layout_marginleft="16dp" android:layout_marginright="16dp" android:layout_margintop="16dp" android:layout_marginbottom="16dp" android:text="语音课堂"/> </relativelayout> <view android:layout_width="fill_parent" android:layout_height="0.1dp" android:background="#b4b4b4" android:layout_marginleft="16dp" android:layout_marginright="16dp"/> <relativelayout android:id="@+id/layout_video" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/white"> <textview android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentstart="true" android:layout_centerinparent="true" android:textsize="16sp" android:textcolor="@color/black" android:layout_marginleft="16dp" android:layout_marginright="16dp" android:layout_margintop="16dp" android:layout_marginbottom="16dp" android:text="视频课堂"/> </relativelayout> <view android:layout_width="fill_parent" android:layout_height="0.1dp" android:background="#b4b4b4" android:layout_marginleft="16dp" android:layout_marginright="16dp"/> <relativelayout android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/white"> <button android:id="@+id/cancel" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="取消" android:layout_marginleft="16dp" android:layout_marginright="16dp" android:layout_margintop="16dp" android:layout_marginbottom="16dp"/> </relativelayout> </linearlayout>
dialog实现源码:
初始化:
private void dialogselectcallinit() { dialogselectcall = new dialog(this, r.style.dialogpopbottom); view inflate = layoutinflater.from(this).inflate(r.layout.dialog_select_call, null); dialogselectcall.setcontentview(inflate); window dialogwindow = dialogselectcall.getwindow(); dialogwindow.setgravity(gravity.bottom); windowmanager.layoutparams lp = dialogwindow.getattributes(); lp.x = 0; lp.y = 0; lp.width = getresources().getdisplaymetrics().widthpixels; dialogwindow.setattributes(lp); relativelayout layoutvoice = (relativelayout) inflate.findviewbyid(r.id.layout_voice); relativelayout layoutvideo = (relativelayout) inflate.findviewbyid(r.id.layout_video); button buttoncancel = (button) inflate.findviewbyid(r.id.cancel); rxview.clicks(layoutvoice) .throttlefirst(2, timeunit.seconds) .compose(this.binduntilevent(activityevent.destroy)) .subscribe(v -> { // dialogselectcall.cancel(); voicesessionactivity.startactivitycallout(this, userid); }); rxview.clicks(layoutvideo) .throttlefirst(2, timeunit.seconds) .compose(this.binduntilevent(activityevent.destroy)) .subscribe(v -> { // dialogselectcall.cancel(); // videosessionactivity.startactivitycallout(this, userid); }); rxview.clicks(buttoncancel) .throttlefirst(2, timeunit.seconds) .compose(this.binduntilevent(activityevent.destroy)) .subscribe(v -> dialogselectcall.cancel()); rxview.touches(layoutvoice, motionevent -> { deallayouttouch(layoutvoice, motionevent); return false; }).compose(this.binduntilevent(activityevent.destroy)).subscribe(motionevent -> {}); rxview.touches(layoutvideo, motionevent -> { deallayouttouch(layoutvideo, motionevent); return false; }).compose(this.binduntilevent(activityevent.destroy)).subscribe(motionevent -> {}); } private void deallayouttouch(view v, motionevent event) { switch (event.getaction()) { case motionevent.action_down: v.setbackgroundcolor(color.rgb(200, 200, 200)); break; case motionevent.action_up: v.setbackgroundcolor(color.white); break; } }
显示对话框:
dialogselectcall.show()
dialogfragment实现源码:
定义了一个类selectcalldialog.java继承dialogfragment
package com.bazhangkeji.classroom.common; import android.app.dialog; import android.app.fragmentmanager; import android.graphics.color; import android.os.bundle; import android.support.annotation.nonnull; import android.view.gravity; import android.view.layoutinflater; import android.view.motionevent; import android.view.view; import android.view.viewgroup; import android.view.window; import android.view.windowmanager; import android.widget.button; import android.widget.relativelayout; import com.bazhangkeji.classroom.r; import com.bazhangkeji.classroom.session.videosessionactivity; import com.bazhangkeji.classroom.session.voicesessionactivity; import com.jakewharton.rxbinding2.view.rxview; import com.trello.rxlifecycle2.android.fragmentevent; import com.trello.rxlifecycle2.components.rxdialogfragment; import java.util.concurrent.timeunit; public class selectcalldialog extends rxdialogfragment { private dialog dialog; private string userid; /** * 初始化.必须调用一次 * @param userid: 目标用户id */ public void init(string userid) { this.userid = userid; } @nonnull @override public dialog oncreatedialog(bundle savedinstancestate) { dialog = new dialog(getactivity(), r.style.dialogpopbottom); view inflate = layoutinflater.from(getactivity()).inflate(r.layout.dialog_select_call, null); dialog.setcontentview(inflate); dialog.setcanceledontouchoutside(true); window window = dialog.getwindow(); windowmanager.layoutparams lp = window.getattributes(); lp.gravity = gravity.bottom; lp.width = windowmanager.layoutparams.match_parent; window.setattributes(lp); relativelayout layoutvoice = (relativelayout) inflate.findviewbyid(r.id.layout_voice); relativelayout layoutvideo = (relativelayout) inflate.findviewbyid(r.id.layout_video); button buttoncancel = (button) dialog.findviewbyid(r.id.cancel); rxview.clicks(layoutvoice) .throttlefirst(2, timeunit.seconds) .compose(this.binduntilevent(fragmentevent.destroy)) .subscribe(v -> { dialog.cancel(); voicesessionactivity.startactivitycallout(getactivity(), userid); }); rxview.clicks(layoutvideo) .throttlefirst(2, timeunit.seconds) .compose(this.binduntilevent(fragmentevent.destroy)) .subscribe(v -> { dialog.cancel(); videosessionactivity.startactivitycallout(getactivity(), userid); }); rxview.clicks(buttoncancel) .throttlefirst(2, timeunit.seconds) .compose(this.binduntilevent(fragmentevent.destroy)) .subscribe(v -> dialog.cancel()); rxview.touches(layoutvoice, motionevent -> { deallayouttouch(layoutvoice, motionevent); return false; }).compose(this.binduntilevent(fragmentevent.destroy)).subscribe(motionevent -> {}); rxview.touches(layoutvideo, motionevent -> { deallayouttouch(layoutvideo, motionevent); return false; }).compose(this.binduntilevent(fragmentevent.destroy)).subscribe(motionevent -> {}); return dialog; } private void deallayouttouch(view v, motionevent event) { switch (event.getaction()) { case motionevent.action_down: v.setbackgroundcolor(color.rgb(200, 200, 200)); break; case motionevent.action_up: v.setbackgroundcolor(color.white); break; } } }
显示对话框前初始化参数:
selectcalldialog.init(userid);
显示对话框后:
selectcalldialog.show(getfragmentmanager(), "");
