Android 自定義彈出菜單和對(duì)話框功能實(shí)例代碼

發(fā)布時(shí)間:2020-10-12 06:07:06 來(lái)源:腳本之家 閱讀:177 作者:cx羽 欄目:移動(dòng)開(kāi)發(fā)

Android 開(kāi)發(fā)當(dāng)中,可能會(huì)存在許多自定義布局的需求,比如自定義彈出菜單(popupWindow),以及自定義對(duì)話框(Dialog)。

話不多說(shuō),直接上圖片。

Android 自定義彈出菜單和對(duì)話框功能實(shí)例代碼 


Android 自定義彈出菜單和對(duì)話框功能實(shí)例代碼

先講第一種,自定義PopUpWindow

1.popupWindow

protected void showPopWindow(View view, final int pos){
  WindowManager wm= (WindowManager) myContext.getSystemService(Context.WINDOW_SERVICE);
  int width=wm.getDefaultDisplay().getWidth();
  LayoutInflater layoutInflater=(LayoutInflater)myContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  View popView=layoutInflater.inflate(R.layout.layout_shoucang_popupwindow,null);
  //加載彈出菜單的布局文件
  final ListView lvpop= (ListView) popView.findViewById(R.id.lvShouCangPop);
  List<String> strData=new ArrayList<>();
  strData.add("刪除");
  strData.add("分享");
  popView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
  popupWindow=new PopupWindow(popView,3*width/10, ViewGroup.LayoutParams.WRAP_CONTENT); //設(shè)置popupWindow 的大小
  lvpop.setAdapter(new AdapterShouCangDeletePop(myContext,strData));
  lvpop.setOnItemClickListener(new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    if(position==0){
     //點(diǎn)擊刪除按鈕的邏輯
//     ToastUtil.toastButtom(myContext,"點(diǎn)擊刪除按鈕");
//     datas.remove(pos); //remove掉這行數(shù)據(jù)
     toActivityPos=pos;
//     notifyDataSetChanged();
     sendDeleteBoardCast(); //發(fā)送一條廣播
     popupWindow.dismiss();
    }else if(position ==1){
     //點(diǎn)擊分享的邏輯
     String title=datas.get(position).ucDesc;
     String photoUrl=datas.get(position).ucIcon;
     String contentUrl=datas.get(position).ucUrl;
     DialogShouCangShare dialogShouCangShare=new DialogShouCangShare(myContext,title,photoUrl,contentUrl); //彈出分享對(duì)話框
     dialogShouCangShare.show();
     popupWindow.dismiss();
    }
   }
  });
  int[] location=new int[2];
  view.getLocationOnScreen(location);
  popupWindow.setFocusable(true);
  popupWindow.setBackgroundDrawable(new BitmapDrawable());//最好加上這一句,因?yàn)樗梢匀∠@示這個(gè)彈出菜單,不加的話,彈出菜單很難消失
  //下方:popupWindow.showAsDropDown(v);
  //popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, location[0]+v.getWidth(), location[1]); 顯示在右邊
  //popupWindow顯示在左邊
  popupWindow.showAtLocation(view, Gravity.NO_GRAVITY
    , location[0]-popupWindow.getWidth(),location[1]); //這里的view是傳進(jìn)來(lái)的view,比如點(diǎn)擊事件中的view,就把它傳進(jìn)來(lái),popupwindow的位置可以自行調(diào)整
 }

彈出菜單的布局,用listView 填充,然后由于要加圓角的背景,所以更改background

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent">
 <ListView
  android:id="@+id/lvShouCangPop"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:padding="2dp"
  android:background="@drawable/bg_shoucang_popup_bg"
  android:listSelector="@drawable/izd_shoucang_delete_selector_pop"
  />
</LinearLayout>

listView的圓角背景圖片

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item>
  <shape
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:shape="rectangle" >
   <solid android:color="#eeeeee"/>
   <corners android:radius="8.0dip"/>
  </shape>
 </item>
</selector>

然后你只要在你的邏輯代碼中調(diào)用showPopWindow()這個(gè)方法就行了,是不是很簡(jiǎn)單!

緊接著開(kāi)始講自定義對(duì)話框了,因?yàn)楹芏郺pp中都有這個(gè)功能,而且效果還不錯(cuò)!

public class DialogShouCangShare extends Dialog{
 private Context myContext;
 private RelativeLayout rlCancle;
 private GridView gridView;
 //那些圖片
 private int[] data=new int[]{R.drawable.izd_shoucang_wechat,R.drawable.izd_shoucang_friend,R.drawable.izd_shoucang_qq,
   R.drawable.izd_shoucang_weibo,R.drawable.izd_shoucang_qzone,R.drawable.izd_shoucang_email};
 public DialogShouCangShare(Context context,String title,String photoUrl,String contentUrl) {
  super(context);
 }
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  super.setContentView(R.layout.izd_shoucang_dialog_share);
  ShareSDK.initSDK(myContext);
  gridView = (GridView) super.findViewById(R.id.gv_share);
  gridView.setSelector(new ColorDrawable(Color.TRANSPARENT));
  AdapterSCShareGridView adapter=new AdapterSCShareGridView(myContext,data);
  gridView.setAdapter(adapter);
  gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> parent, View view,
         int position, long id) {
    switch (position) {
     //對(duì)于GridView中的item的點(diǎn)擊事件
    }
    DialogShouCangShare.this.dismiss();
   }
  });
  rlCancle = (RelativeLayout) findViewById(R.id.shoucang_rlCancle);
  rlCancle.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    DialogShouCangShare.this.dismiss();
   }
  });
 @Override
 public void show()
 {
  this.requestWindowFeature(Window.FEATURE_NO_TITLE);
  this.requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
  this.setCanceledOnTouchOutside(true);
  Window dialogWindow = this.getWindow(); //得到對(duì)話框
  dialogWindow.setGravity(Gravity.LEFT | Gravity.BOTTOM);
  dialogWindow.getDecorView().setPadding(0, 0, 0, 0);
  WindowManager.LayoutParams lp = dialogWindow.getAttributes();
  lp.width = WindowManager.LayoutParams.MATCH_PARENT;
  lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
  dialogWindow.setAttributes(lp);
  dialogWindow.setWindowAnimations(R.style.izd_dialogWindowAnim); //設(shè)置窗口彈出動(dòng)畫(huà) ,由styles配置,有進(jìn)入和退出動(dòng)畫(huà)
  //dialogWindow.setWindowAnimations(R.anim.dialog_enter_anim);
  //
  //  WindowManager.LayoutParams lp = dialogWindow.getAttributes();
  //  lp.width = 100; // 寬度
  //  lp.height = 300; // 高度
  //  //lp.alpha = 0.7f; // 透明度
  //  //dialogWindow.setAttributes(lp);
  dialogWindow.setBackgroundDrawableResource(R.drawable.radius_shoucang_share_nopadding); //設(shè)置對(duì)話框背景
//  dialogWindow.setBackgroundDrawableResource(R.color.izd_white); //設(shè)置對(duì)話框背景
  super.show();
 }
}

再看下該對(duì)話框的布局文件:只有一個(gè)gridView 和relativeLayout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical"
 android:layout_marginTop="10dp"
 android:layout_marginLeft="10dp"
 android:layout_marginRight="10dp"
 android:layout_marginBottom="8dp"
 android:background="@color/transparent"
 >
 <LinearLayout
  android:layout_width="match_parent"
  android:orientation="vertical"
  android:layout_height="match_parent">
  <GridView
   android:id="@+id/gv_share"
   android:layout_width="match_parent"
   android:layout_height="0dp"
   android:layout_weight="1"
   android:numColumns="3"
   android:verticalSpacing="-36dp"
   android:background="@drawable/bg_share_shoucang">
  </GridView>
  <RelativeLayout
   android:id="@+id/shoucang_rlCancle"
   android:layout_width="match_parent"
   android:layout_height="48dp"
   android:layout_marginTop="8dp"
   android:background="@drawable/bg_share_shoucang"
   >
   <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="取消"
    android:textColor="#009688"
    android:textSize="16sp"
    android:layout_centerInParent="true"/>
  </RelativeLayout>
 </LinearLayout>
</LinearLayout>

這是設(shè)置對(duì)話框的背景的布局文件,其實(shí)主要設(shè)置對(duì)話框的圓角,以及對(duì)話框顏色為透明就行了!

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
 <solid android:color="#ffffff"/>
 <corners android:radius="4dp" />
 <gradient android:startColor="#00000000" android:endColor="#00000000"/>
</shape>

再次聲明,這里使用GridView是為了,方便以后填充更多的數(shù)據(jù),如果用相對(duì)布局加線性布局,寫(xiě)死的話,以后若要再次添加數(shù)據(jù)的話,就要再去修改布局,比較麻煩!因?yàn)橛星败囍b的我,下面就是我之前不用GridView去寫(xiě)的布局文件!新手如果想練手的話,可以嘗試!

效果也是一樣的!

Android 自定義彈出菜單和對(duì)話框功能實(shí)例代碼

然后你要使用該對(duì)話框的話,只要新建對(duì)話框就可以了!

DialogShouCangShare dialogShouCangShare=new DialogShouCangShare(myContext); //彈出分享對(duì)話框 
dialogShouCangShare.show();

總結(jié)
