Android实现可输入数据的弹出框

之前一篇文章，介绍了如何定义从屏幕底部弹出popupwindow即《android animation实战之屏幕底部弹出popupwindow》，写完之后，突然想起之前写过自定义内容显示的弹出框，就随手写了两个实例，分享出来：

第一种实现方式：继承dialog
 1.1 线定义弹出框要显示的内容：create_user_dialog.xml

<?xml version="1.0" encoding="utf-8"?> 
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:id="@+id/create_user_dialog_view" 
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content" 
 android:background="@drawable/dialog_load_bg" 
 android:minwidth="200dp" 
 android:orientation="vertical" 
 android:padding="10dp" 
 android:paddingbottom="30dp" 
 android:paddingtop="30dp"> 
 
 <edittext 
  android:id="@+id/text_name" 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:background="@drawable/edit_bg" 
  android:hint="姓名" 
  android:minheight="45dp" 
  android:textsize="18sp" /> 
 
 <edittext 
  android:id="@+id/text_mobile" 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:layout_margintop="5dp" 
  android:background="@drawable/edit_bg" 
  android:hint="手机号" 
  android:minheight="45dp" 
  android:textsize="18sp" /> 
 
 <edittext 
  android:id="@+id/text_info" 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:layout_margintop="5dp" 
  android:background="@drawable/edit_bg" 
  android:gravity="top|left" 
  android:hint="个性签名" 
  android:minheight="145dp" 
  android:textsize="18sp" /> 
 
 <button 
  android:id="@+id/btn_save_pop" 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:layout_margintop="5dp" 
  android:text="保存" /> 
 
</linearlayout> 

 1.2 定义要弹出的dialog

public class createuserdialog extends dialog { 
 
 /** 
  * 上下文对象 * 
  */ 
 activity context; 
 
 private button btn_save; 
 
 public edittext text_name; 
 
 public edittext text_mobile; 
 
 public edittext text_info; 
 
 
 private view.onclicklistener mclicklistener; 
 
 public createuserdialog(activity context) { 
  super(context); 
  this.context = context; 
 } 
 
 public createuserdialog(activity context, int theme, view.onclicklistener clicklistener) { 
  super(context, theme); 
  this.context = context; 
  this.mclicklistener = clicklistener; 
 } 
 
 @override 
 protected void oncreate(bundle savedinstancestate) { 
  super.oncreate(savedinstancestate); 
  // 指定布局 
  this.setcontentview(r.layout.create_user_dialog); 
 
  text_name = (edittext) findviewbyid(r.id.text_name); 
  text_mobile = (edittext) findviewbyid(r.id.text_mobile); 
  text_info = (edittext) findviewbyid(r.id.text_info); 
 
  /* 
   * 获取圣诞框的窗口对象及参数对象以修改对话框的布局设置, 可以直接调用getwindow(),表示获得这个activity的window 
   * 对象,这样这可以以同样的方式改变这个activity的属性. 
   */ 
  window dialogwindow = this.getwindow(); 
 
  windowmanager m = context.getwindowmanager(); 
  display d = m.getdefaultdisplay(); // 获取屏幕宽、高用 
  windowmanager.layoutparams p = dialogwindow.getattributes(); // 获取对话框当前的参数值 
  // p.height = (int) (d.getheight() * 0.6); // 高度设置为屏幕的0.6 
  p.width = (int) (d.getwidth() * 0.8); // 宽度设置为屏幕的0.8 
  dialogwindow.setattributes(p); 
 
  // 根据id在布局中找到控件对象 
  btn_save = (button) findviewbyid(r.id.btn_save); 
 
  // 为按钮绑定点击事件监听器 
  btn_save.setonclicklistener(mclicklistener); 
 
  this.setcancelable(true); 
 } 
} 

1.3 调用弹出框

public void showeditdialog(view view) { 
 createuserdialog = new createuserdialog(this,r.style.loading_dialog,onclicklistener); 
 createuserdialog.show(); 
} 



private view.onclicklistener onclicklistener = new view.onclicklistener() { 
  @override 
  public void onclick(view v) { 
 
   switch (v.getid()) { 
    case r.id.btn_save: 
 
     string name = createuserdialog.text_name.gettext().tostring().trim(); 
     string mobile = createuserdialog.text_mobile.gettext().tostring().trim(); 
     string info = createuserdialog.text_info.gettext().tostring().trim(); 
 
     system.out.println(name+"——"+mobile+"——"+info); 
     break; 
   } 
  } 
 }; 

第二种实现方式：继承popupwindow
2.1 定义弹出框布局文件，和1.1定义的一致
2.2 定义要弹出的popupwindow

public class createuserpopwin extends popupwindow { 
 
 private context mcontext; 
 
 private view view; 
 
 private button btn_save_pop; 
 
 public edittext text_name; 
 
 public edittext text_mobile; 
 
 public edittext text_info; 
 
 
 public createuserpopwin(activity mcontext, view.onclicklistener itemsonclick) { 
 
  this.mcontext = mcontext; 
 
  this.view = layoutinflater.from(mcontext).inflate(r.layout.create_user_pop, null); 
 
  text_name = (edittext) view.findviewbyid(r.id.text_name); 
  text_mobile = (edittext) view.findviewbyid(r.id.text_mobile); 
  text_info = (edittext) view.findviewbyid(r.id.text_info); 
 
  btn_save_pop = (button) view.findviewbyid(r.id.btn_save_pop); 
 
  // 设置按钮监听 
  btn_save_pop.setonclicklistener(itemsonclick); 
 
  // 设置外部可点击 
  this.setoutsidetouchable(true); 
 
 
  /* 设置弹出窗口特征 */ 
  // 设置视图 
  this.setcontentview(this.view); 
 
  // 设置弹出窗体的宽和高 
   /* 
   * 获取圣诞框的窗口对象及参数对象以修改对话框的布局设置, 可以直接调用getwindow(),表示获得这个activity的window 
   * 对象,这样这可以以同样的方式改变这个activity的属性. 
   */ 
  window dialogwindow = mcontext.getwindow(); 
 
  windowmanager m = mcontext.getwindowmanager(); 
  display d = m.getdefaultdisplay(); // 获取屏幕宽、高用 
  windowmanager.layoutparams p = dialogwindow.getattributes(); // 获取对话框当前的参数值 
 
  this.setheight(relativelayout.layoutparams.wrap_content); 
  this.setwidth((int) (d.getwidth() * 0.8)); 
 
  // 设置弹出窗体可点击 
  this.setfocusable(true); 
 
 } 
} 

2.3 调用该弹框组件

public void showeditpopwin(view view) { 
 
  createuserpopwin = new createuserpopwin(this,onclicklistener); 
 
  createuserpopwin.showatlocation(findviewbyid(r.id.main_view), gravity.center, 0, 0); 
 } 


private view.onclicklistener onclicklistener = new view.onclicklistener() { 
  @override 
  public void onclick(view v) { 
 
   switch (v.getid()) { 
    case r.id.btn_save_pop: 
 
     string name1 = createuserpopwin.text_name.gettext().tostring().trim(); 
     string mobile1 = createuserpopwin.text_mobile.gettext().tostring().trim(); 
     string info1 = createuserpopwin.text_info.gettext().tostring().trim(); 
 
     system.out.println(name1+"——"+mobile1+"——"+info1); 
 
     createuserpopwin.dismiss(); 
     break; 
   } 
  } 
 };
