Android⾃定义密码输⼊框⼀、前⾔：我们在软件开发过程中，经常会遇到密码输⼊框，这就要我们⾃定控件来实现，下⾯的⾃定义密码框，是参考我的同事写出来的，今天分享⼀下。1. gitHub 地址：/lyyRunning/PasswordBoxDemo2. 效果图如下：图 图 图 图 ⼆、使⽤ ：我只介绍第⼆种，第⼀种是弹窗，回调有点多，⼤家可以下载源码看⼀下啊。强⼤⼯具类依赖：（⾃定义布局⽤不到，⽤到了弹窗和键盘的显⽰隐藏）implementation ':utilcode:1.25.2'ivity调⽤：public class TwoActivity extends Activity { @BindView(tionCode) ActivationCodeBox activationCode; @BindView(_cancel) Button btnCancel; @BindView(ner) LinearLayout container; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { te(savedInstanceState); setContentView(ty_two); (this); initData(); } private void initData() { //激活码输⼊完成 utCompleteListener(new ompleteListener() { @Override public void inputComplete(String code) { ftInput(); //回调进⼊ Activity if (("1234")) { //激活成功 ort("激活成功"); p(false, ""); } else { //激活失败 ort("激活失败"); p(true, "激活失败"); } } }); //返回上⼀页 lickListener(new kListener() { @Override public void onClick(View v) { (); } }); } /** * 页⾯跳转 * * @param mContext */ public static void launch(Context mContext) { Intent intent = new Intent(mContext, ); ctivity(intent); }2.⾃定义ActivationCodeBox布局：public class ActivationCodeBox extends RelativeLayout { private Context context; private TextView[] textViews; private static int MAXlength = 4; private static int MAXlength = 4; private TextView tvTip; private String inputContent; private EditText etCode; private List codes = new ArrayList<>(); private InputMethodManager imm; private Animation shake; public ActivationCodeBox(Context context) { super(context); t = context; loadView(); } public ActivationCodeBox(Context context, AttributeSet attrs) { super(context, attrs); t = context; loadView(); } public ActivationCodeBox(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); t = context; loadView(); } @RequiresApi(api = N_OP) public ActivationCodeBox(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { super(context, attrs, defStyleAttr, defStyleRes); t = context; loadView(); } private void loadView(){ //抖动效果 shake = imation(context, ); imm = (InputMethodManager) temService(_METHOD_SERVICE); View view = (context).inflate(tion_code_box, this); initView(view); initEvent(); } private void initView(View view){ textViews = new TextView[MAXlength]; textViews[0] = (TextView) ewById(_code1); textViews[1] = (TextView) ewById(_code2); textViews[2] = (TextView) ewById(_code3); textViews[3] = (TextView) ewById(_code4); etCode = (EditText) ewById(_code); tvTip = (TextView) ewById(_tip); } private void initEvent(){ //验证码输⼊ tChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { } @Override public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) { } @Override public void afterTextChanged(Editable editable) { inputContent = t().toString(); if (inputCompleteListener != null) { if (() >= MAXlength) { omplete(inputContent); } } for (int i = 0; i < MAXlength; i++) { if (i < ()) { textViews[i].setText(f((i))); } else { textViews[i].setText(""); } } } } }); } /** * 设置⾼亮颜⾊ */ private void setColor(boolean isShow, int color){ for (int i = 0; i ty_two布局： 三、总结 ：布局⽅式：密码输⼊框采⽤的的相对布局，让 LinearLayout 中的四个TextView和EditText的布局重复。监听EditText输⼊数据，添加到TextView上。1. 思路：⾃定义ActivationCodeBox实现 RelativeLayout；重写多个构造⽅法，构造⽅法调⽤loadView();loadView() 加载布局，获取各个控件；通过initEvent()⽅法监听数据的输⼊；在showCode()中，把 EditText 输⼊的值，放到对应的 TextVIew 上。
