Android仿支付宝微信支付密码界面弹窗封装dialog
一,功能效果
二,实现过程
1,先写xml文件:dialog_keyboard.xml
注意事项
(1),密码部分用的是一个线性布局中6个TextView,并设置android:inputType="numberPassword",
外框是用的一个有stroke属性的shape,
(2),1-9数字是用的recycleview ,每个item的底部和右边有1dp的黑线,填充后形成分割线。
(3),recycleview 要设置属性 android:overScrollMode="never
不然滑动键盘的时候有阴影
(4),底部三个按钮用的线性布局里的三个TextView
<span style="font-size:14px;"><?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="wrap_content" android:background="@color/bgItemCheck" android:orientation="vertical"> <RelativeLayout android:layout_width="match_parent" android:layout_height="60dp"> <ImageView android:id="@+id/iv_close_key" android:layout_width="45dp" android:layout_height="45dp" android:layout_centerVertical="true" android:padding="10dp" android:src="@mipmap/icon_close" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:text="输入密码" android:textColor="@color/black" android:textSize="20sp" /> <View android:layout_width="match_parent" android:layout_height="1dp" android:layout_alignParentBottom="true" android:background="@color/underLine" /> </RelativeLayout> <TextView android:id="@+id/tv_tip_money" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="15dp" android:gravity="center" android:text="提现金额0元,服务费0元" android:textColor="@color/black" /> <LinearLayout android:layout_width="335dp" android:layout_height="wrap_content" android:layout_gravity="center" android:background="@drawable/shape_bg_psw" android:orientation="horizontal"> <TextView android:id="@+id/tv_first_num" android:layout_width="55dp" android:layout_height="55dp" android:gravity="center" android:inputType="numberPassword" android:textColor="@color/black" android:textSize="30sp" /> <View android:layout_width="1dp" android:layout_height="match_parent" android:background="@color/strokePsw" /> <TextView android:id="@+id/tv_second_num" android:layout_width="55dp" android:layout_height="55dp" android:gravity="center" android:inputType="numberPassword" android:textColor="@color/black" android:textSize="30sp" /> <View android:layout_width="1dp" android:layout_height="match_parent" android:background="@color/strokePsw" /> <TextView android:id="@+id/tv_third_num" android:layout_width="55dp" android:layout_height="55dp" android:gravity="center" android:inputType="numberPassword" android:textColor="@color/black" android:textSize="30sp" /> <View android:layout_width="1dp" android:layout_height="match_parent" android:background="@color/strokePsw" /> <TextView android:id="@+id/tv_fourth_num" android:layout_width="55dp" android:layout_height="55dp" android:gravity="center" android:inputType="numberPassword" android:textColor="@color/black" android:textSize="30sp" /> <View android:layout_width="1dp" android:layout_height="match_parent" android:background="@color/strokePsw" /> <TextView android:id="@+id/tv_fifth_num" android:layout_width="55dp" android:layout_height="55dp" android:gravity="center" android:inputType="numberPassword" android:textColor="@color/black" android:textSize="30sp" /> <View android:layout_width="1dp" android:layout_height="match_parent" android:background="@color/strokePsw" /> <TextView android:id="@+id/tv_sixth_num" android:layout_width="55dp" android:layout_height="55dp" android:gravity="center" android:inputType="numberPassword" android:textColor="@color/black" android:textSize="30sp" /> </LinearLayout> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/tv_forget_psw" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_margin="10dp" android:padding="5dp" android:text="忘记密码?" android:textColor="@color/mainColor" android:textSize="13sp" android:visibility="invisible" /> </RelativeLayout> <android.support.v7.widget.RecyclerView android:id="@+id/rv_keyboard" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="30dp" android:background="@color/white" android:overScrollMode="never" /> <LinearLayout android:layout_width="match_parent" android:layout_height="58dp" android:orientation="horizontal"> <TextView android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@color/bgItemPsw" /> <TextView android:id="@+id/tv_zero" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/selector_bg_psw_item" android:gravity="center" android:text="0" android:textColor="@color/black" android:textSize="25sp" /> <RelativeLayout android:id="@+id/rl_undo" android:layout_width="1dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/selector_bg_undo"> <ImageView android:layout_width="25dp" android:layout_height="match_parent" android:layout_centerInParent="true" android:src="@mipmap/icon_undo" /> </RelativeLayout> </LinearLayout> </LinearLayout></span>
2,Java代码 KeyboardDialog.java
注意事项
(1),封装成dialog,这段代码要在setContentView之前 window.requestFeature(Window.FEATURE_NO_TITLE)
(2),在构造方法中设置样式(后面详述)
(3),适配器是已封装的,用原生的也没差
(4),密码的存储和删除是操作字符串
(5),使用了butterknife 版本为:compile'com.jakewharton:butterknife:7.0.1'
(6),在设置attributes.width = ScreenUtils.getScreenWidth(context);
使用了封装的方法 目的是获取屏幕的宽 可自行百度达到相同效果
<span style="font-size:14px;">public class KeyboardDialog extends Dialog { private final Context context; private final int money; @Bind(R.id.rv_keyboard)//数字列表 RecyclerView rvKeyboard; @Bind(R.id.iv_close_key)//关闭按钮 ImageView ivCloseKey; @Bind(R.id.tv_tip_money)//提现金额及手续费 TextView tvTipMoney; @Bind(R.id.tv_zero)//数字0 TextView tvZero; @Bind(R.id.rl_undo)//后退键 RelativeLayout rlUndo; //六位密码 @Bind(R.id.tv_first_num) TextView tvFirstNum; @Bind(R.id.tv_second_num) TextView tvSecondNum; @Bind(R.id.tv_third_num) TextView tvThirdNum; @Bind(R.id.tv_fourth_num) TextView tvFourthNum; @Bind(R.id.tv_fifth_num) TextView tvFifthNum; @Bind(R.id.tv_sixth_num) TextView tvSixthNum; private ArrayList<String> keyboardList;//数字列表 private String psw = "";//密码 public KeyboardDialog(Context context, int money) { super(context, R.style.keyboard_dialog); this.context = context; this.money = money;//要提现金额 setCanceledOnTouchOutside(true); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Window window = this.getWindow(); assert window != null; window.requestFeature(Window.FEATURE_NO_TITLE); window.setWindowAnimations(R.style.keyboard_dialog_anim); setContentView(R.layout.dialog_keyboard); ButterKnife.bind(this); WindowManager.LayoutParams attributes = window.getAttributes(); attributes.gravity = Gravity.BOTTOM; attributes.width = ScreenUtils.getScreenWidth(context); attributes.height = GridLayoutManager.LayoutParams.WRAP_CONTENT; initData(); } /* * 初始化 * */ private void initData() { keyboardList = new ArrayList<>(); for (int i = 1; i < 10; i++) { keyboardList.add(i + ""); } //设置要提现的金额 tvTipMoney.setText("提现金额" + money + "元"); GridLayoutManager glManager = new GridLayoutManager(context, 3); rvKeyboard.setLayoutManager(glManager); RcyCommonAdapter adapter = getAdapter(); rvKeyboard.setAdapter(adapter); } private RcyCommonAdapter getAdapter() { return new RcyCommonAdapter<String>(context, keyboardList, false, rvKeyboard) { @Override public void convert(RcyViewHolder holder, String keyboard) { TextView tvKeyboard = holder.getView(R.id.tv_keyboard_item); tvKeyboard.setText(keyboard); } @Override public int getmLayoutId(int position) { return R.layout.item_keyboard; } @Override public void onItemClickListener(int position) { inputNum(position + 1 + ""); } }; } /* * 输入密码 先判断现有密码长度并设置显示输入了密码 添加密码到密码字符串 * 后判断输入后密码的长度 如果等于6则关闭并请求服务器 * */ private void inputNum(String num) { switch (psw.length()) { case 0: tvFirstNum.setText(num); break; case 1: tvSecondNum.setText(num); break; case 2: tvThirdNum.setText(num); break; case 3: tvFourthNum.setText(num); break; case 4: tvFifthNum.setText(num); break; case 5: tvSixthNum.setText(num); break; } psw += num; if (psw.length() == 6) { //TODO 请求服务器 密码为 psw Log.d("psw", psw); dismiss(); } } @OnClick({R.id.iv_close_key, R.id.tv_zero, R.id.rl_undo}) public void onClick(View view) { switch (view.getId()) { case R.id.iv_close_key://关闭dialog dismiss(); break; case R.id.tv_zero://输入0 inputNum("0"); break; case R.id.rl_undo://删除输入的密码 deleteNum(); break; } } /* * 删除密码 根据已输入的密码长度将对应的textview设置为空 * 并将密码字符串最后一位切割掉 * */ private void deleteNum() { switch (psw.length()) { case 1: tvFirstNum.setText(""); psw = ""; break; case 2: tvSecondNum.setText(""); psw = psw.substring(0, 1); break; case 3: tvThirdNum.setText(""); psw = psw.substring(0, 2); break; case 4: tvFourthNum.setText(""); psw = psw.substring(0, 3); break; case 5: tvFifthNum.setText(""); psw = psw.substring(0, 4); break; } } }</span><span style="font-size:18px;"> </span>
3,设置弹框样式
(1),在构造方法中设置样式 R.style.keyboard_dialog
<span style="font-size:14px;">public KeyboardDialog(Context context, int money) { super(context, R.style.keyboard_dialog); this.context = context; this.money = money;//要提现金额 setCanceledOnTouchOutside(true); }</span>
样式代码为
<span style="font-size:14px;"><style name="keyboard_dialog" parent="AppTheme.base"> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowFrame">@null</item> <item name="android:windowNoTitle">true</item> <item name="android:windowIsFloating">true</item> <item name="android:windowIsTranslucent">true</item> <item name="android:windowContentOverlay">@null</item> <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item> <item name="android:backgroundDimEnabled">true</item> </style></span>
(2),在onCreate方法中设置弹框动画样式
<span style="font-size:14px;">window.setWindowAnimations(R.style.keyboard_dialog_anim);</span>
样式代码为
<span style="font-size:14px;"><style name="keyboard_dialog_anim"> <item name="android:windowEnterAnimation">@anim/enter_dialog_anim</item> <item name="android:windowExitAnimation">@anim/exit_dialog_anim</item> </style></span>
三,调用
调用很简单 一行就可以 需要返回数据就需要自行添加了
<span style="font-size:14px;"> new KeyboardDialog(this, 1000).show();</span>
