先来个效果图让大家看一看，现在好多app都用类似的注册页
实现思路
自定义EditText的布局
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
style
View的代码
private EditText editText;
private TextView[] TextViews;
private StringBuffer stringBuffer = new StringBuffer();
private int count = 4;
private String inputContent;
public SecurityCodeView(Context context) {
this(context, null);
}
public SecurityCodeView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public SecurityCodeView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
TextViews = new TextView[4];
View.inflate(context, R.layout.view_security_code, this);
editText = (EditText) findViewById(R.id.item_edittext);
TextViews[0] = (TextView) findViewById(R.id.item_code_iv1);
TextViews[1] = (TextView) findViewById(R.id.item_code_iv2);
TextViews[2] = (TextView) findViewById(R.id.item_code_iv3);
TextViews[3] = (TextView) findViewById(R.id.item_code_iv4);
editText.setCursorVisible(false);//将光标隐藏
setListener();
}
/**
* 清空输入内容
*/
public void clearEditText() {
stringBuffer.delete(0, stringBuffer.length());
inputCOntent= stringBuffer.toString();
for (int i = 0; i
监听代码
private void setListener() {
editText.addTextChangedListener(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) {
//重点 如果字符不为""时才进行操作
if (!editable.toString().equals("")) {
if (stringBuffer.length() > 3) {
//当文本长度大于3位时edittext置空
editText.setText("");
return;
} else {
//将文字添加到StringBuffer中
stringBuffer.append(editable);
editText.setText("");//添加后将EditText置空 造成没有文字输入的错局
// Log.e("TAG", "afterTextChanged: stringBuffer is " + stringBuffer);
count = stringBuffer.length();//记录stringbuffer的长度
inputCOntent= stringBuffer.toString();
if (stringBuffer.length() == 4) {
//文字长度位4 则调用完成输入的监听
if (inputCompleteListener != null) {
inputCompleteListener.inputComplete();
}
}
}
for (int i = 0; i 0) {
//删除相应位置的字符
stringBuffer.delete((count - 1), count);
count--;
// Log.e(TAG, "afterTextChanged: stringBuffer is " + stringBuffer);
inputCOntent= stringBuffer.toString();
TextViews[stringBuffer.length()].setText("");
TextViews[stringBuffer.length()].setBackgroundResource(R.mipmap.bg_verify);
if (inputCompleteListener != null)
inputCompleteListener.deleteContent(true);//有删除就通知manger
}
return false;
}
自定义的EditText到这了算是结束了
弹出框的布局
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
[大体的思路,点击事件之后弹出一个Dialog,然后再这个页面进行注册,有可能这个Dialog会复用,或者改一些样式(采用Builder设计模式)]
接下来自定义Dialog
要实现EditText的两个接口
public class XyAlertDialog extends DialogFragment implements SecurityCodeView.InputCompleteListener {
private SecurityCodeView editText;
private TextView text;
private TextView tv_title;
private ImageView img_close;
public static final String TAG = XyAlertDialog.class.getSimpleName();
private Builder builder;
private static XyAlertDialog instance = new XyAlertDialog();
private TextView tv_phone;
private TextView tv_click;
public static XyAlertDialog getInstance() {
return instance;
}
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
this.setCancelable(true);
setRetainInstance(true);
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
try {
if (isAdded() && getActivity() != null)
if (builder != null)
builder = (Builder) savedInstanceState.getSerializable(Builder.class.getSimpleName());
} catch (Exception e) {
}
}
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
try {
if (isAdded() && getActivity() != null)
if (builder != null)
outState.putSerializable(Builder.class.getSimpleName(), builder);
} catch (Exception e) {
Log.d(TAG, e.toString());
}
}
@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
dialog.setCanceledOnTouchOutside(false);//点击旁白不消失
return dialog;
}
@Nullable
@Override

container, @Nullable Bundle savedInstanceState) {
