Android仿支付宝微信支付密码界面弹窗封装dialog

作者:Aragon_

这篇文章主要介绍了Android仿支付宝微信支付密码界面弹窗封装dialog的实例代码,非常不错,具有参考借鉴价值,需要的朋友可以参考下

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

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>
