Android自定義View實現微信支付密碼輸入框

本文實例為大家分享了Android實現微信支付密碼輸入框的具體代碼，供大家參考，具體內容如下

效果圖

項目中使用到了支付密碼功能，其實這類界面是比較常用的，涉及支付密碼的輸入的一般都會用到對的，所以單獨地把這部分抽取出來，有需要的朋友可以拿去用哈!

效果就是支付,彈出密碼框,輸入密碼,這個過程密碼不可見,并且提供一個輸入完畢的監聽!

這個彈出層呢,其實就是一個DialogFragment，邏輯封裝在其內部

一.彈出層進出動畫 (anim文件)

push_bottom_in.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- 上下滑入式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
 <translate
 android:duration="200"
 android:fromYDelta="100%p"
 android:toYDelta="0" />
</set>

push_bottom_out.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- 上下滑出式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
 <translate
 android:duration="200"
 android:fromYDelta="0"
 android:toYDelta="100%p" />
</set>

二.drawable資源

selector_item_pressed.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:drawable="@color/gray_bg" android:state_pressed="true" />
 <item android:drawable="@color/white" android:state_activated="false" />
 <item android:drawable="@color/white" />
</selector>

鍵盤的點擊效果

shape_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
 android:shape="rectangle">
 <solid android:color="@android:color/white" />
 <corners android:radius="10dp" />
</shape>

彈出框樣式

三.mipmap資源

九.密碼框view

 //先畫個圓角矩形

十.支付彈出層

public class PayFragment extends DialogFragment implements View.OnClickListener {

 public static final String EXTRA_CONTENT = "extra_content"; //提示框內容
 public static final String EXTRA_CONTENT2 = "extra_content2"; //提示框內容
 public static final String EXTRA_CONTENT3 = "extra_content3"; //提示框內容

 private PayPassWordView psw_input;
 private PayPassWordView.InputCallBack inputCallBack;

 @NonNull
 @Override
 public Dialog onCreateDialog(Bundle savedInstanceState) {
 // 使用不帶Theme的構造器, 獲得的dialog邊框距離屏幕仍有幾毫米的縫隙。
 Dialog dialog = new Dialog(getActivity(), R.style.BottomDialog);
 dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); // 設置Content前設定
 dialog.setContentView(R.layout.fragment_pay);
 dialog.setCanceledOnTouchOutside(true); //外部點擊取消
 // 設置寬度為屏寬, 靠近屏幕底部。
 final Window window = dialog.getWindow();
 window.setWindowAnimations(R.style.AnimBottom);
 window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
 final WindowManager.LayoutParams lp = window.getAttributes();
 lp.width = WindowManager.LayoutParams.MATCH_PARENT; // 寬度持平
 lp.gravity = Gravity.TOP;
 window.setAttributes(lp);
 initView(dialog);
 return dialog;
 }

 private void initView(Dialog dialog) {
 Bundle bundle = getArguments();
 if (bundle != null) {
 TextView tv_content = (TextView) dialog.findViewById(R.id.tv_content);
 TextView tv_content2 = (TextView) dialog.findViewById(R.id.tv_content2);
 TextView tv_content3 = (TextView) dialog.findViewById(R.id.tv_content3);
 tv_content.setText(bundle.getString(EXTRA_CONTENT));
 tv_content2.setText(bundle.getString(EXTRA_CONTENT2));
 tv_content3.setText(bundle.getString(EXTRA_CONTENT3));
 }
 psw_input = (PayPassWordView) dialog.findViewById(R.id.payPwdView);
 PassWordInputView inputMethodView = (PassWordInputView) dialog.findViewById(R.id.inputMethodView);
 psw_input.setInputMethodView(inputMethodView);
 psw_input.setInputCallBack(inputCallBack);
 dialog.findViewById(R.id.iv_close).setOnClickListener(this);
 }

 @Override
 public void onClick(View v) {
 switch (v.getId()) {
 case R.id.iv_close:
 dismiss();
 break;
 }
 }

 /**
 * 設置輸入回調
 *
 * @param inputCallBack
 */
 public void setPaySuccessCallBack(PayPassWordView.InputCallBack inputCallBack) {
 this.inputCallBack = inputCallBack;
 }

}

十一.邏輯代碼中直接引用

public class MainActivity extends AppCompatActivity implements PayPassWordView.InputCallBack, View.OnClickListener {

 private PayFragment fragment;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 findViewById(R.id.btn_pay).setOnClickListener(this);
 }

 @Override
 public void onClick(View v) {
 switch (v.getId()) {
 case R.id.btn_pay:
 Bundle bundle = new Bundle();
 bundle.putString(PayFragment.EXTRA_CONTENT, "提現");
 bundle.putString(PayFragment.EXTRA_CONTENT2, "¥" + 1.00);
 bundle.putString(PayFragment.EXTRA_CONTENT3, "額外扣除0.1手續費");
 fragment = new PayFragment();//創建支付彈出框實例
 fragment.setArguments(bundle);//傳遞信息
 fragment.setPaySuccessCallBack(MainActivity.this);//設置回調
 fragment.show(getSupportFragmentManager(), "Pay");
 break;
 }
 }


 @Override
 public void onInputFinish(String result) {
 Toast.makeText(this, result, Toast.LENGTH_SHORT).show();
 fragment.dismiss();//窗口消失
 }
}

什么都沒有，只有一個點擊事件而已.

分享結束，這里面的代碼可是有我造假的成分哦，不過，我就是喜歡將優秀的東西集成在一起，謝謝觀看！

以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持億速云。
