Android自定義方框EditText註冊驗證碼
阿新 • • 發佈：2019-01-10
先來個效果圖讓大家看一看,現在好多app都用類似的註冊頁
實現思路
用一個透明的EditText與四個TextView重疊，並給TextView設定預設背景
第4個TextView輸入完成後,要設定回撥,並且要加入增加刪除的回撥
還要監聽EditText內容的變化,獲取內容,並且改變EditText下面的TextView的顏色
重新發送的是採用一個自定義的CountDownTimer類
彈出效果自定義的一個Dialog繼承DialogFragment
自定義EditText的佈局
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout style
<style name="text_editStyle" >
<item name="android:layout_height">47dp</item>
<item name="android:layout_width">47dp</item>
<item name="android:background">@mipmap/bg_verify</item>
<item name="android:gravity">center</item>
<item name="android:textColor">@color/common_blue_0090FF</item>
<item name="android:textSize">18sp</item>
</style>View的程式碼
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);//將游標隱藏
setListener();
}
/**
* 清空輸入內容
*/
public void clearEditText() {
stringBuffer.delete(0, stringBuffer.length());
inputContent = stringBuffer.toString();
for (int i = 0; i < TextViews.length; i++) {
TextViews[i].setText("");
TextViews[i].setBackgroundResource(R.mipmap.bg_verify);
}
}
private InputCompleteListener inputCompleteListener;
public void setInputCompleteListener(InputCompleteListener inputCompleteListener) {
this.inputCompleteListener = inputCompleteListener;
}
public interface InputCompleteListener {
void inputComplete();
void deleteContent(boolean isDelete);
}
/**
* 獲取輸入文字
*
* @return
*/
public String getEditContent() {
return inputContent;
}監聽程式碼
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) {
//重點 如果字元不為""時才進行操作
if (!editable.toString().equals("")) {
if (stringBuffer.length() > 3) {
//當文字長度大於3位時edittext置空
editText.setText("");
return;
} else {
//將文字新增到StringBuffer中
stringBuffer.append(editable);
editText.setText("");//新增後將EditText置空 造成沒有文字輸入的錯局
// Log.e("TAG", "afterTextChanged: stringBuffer is " + stringBuffer);
count = stringBuffer.length();//記錄stringbuffer的長度
inputContent = stringBuffer.toString();
if (stringBuffer.length() == 4) {
//文字長度位4 則呼叫完成輸入的監聽
if (inputCompleteListener != null) {
inputCompleteListener.inputComplete();
}
}
}
for (int i = 0; i < stringBuffer.length(); i++) {
TextViews[i].setText(String.valueOf(inputContent.charAt(i)));
TextViews[i].setBackgroundResource(R.mipmap.bg_verify_press);
}
}
}
});
editText.setOnKeyListener(new OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_DEL
&& event.getAction() == KeyEvent.ACTION_DOWN) {
if (onKeyDelete()) return true;
return true;
}
return false;
}
});
}
public boolean onKeyDelete() {
if (count == 0) {
count = 4;
return true;
}
if (stringBuffer.length() > 0) {
//刪除相應位置的字元
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);//有刪除就通知manger
}
return false;
}自定義的EditText到這了算是結束了
彈出框的佈局

</LinearLayout>[大體的思路,點選事件之後彈出一個Dialog,然後再這個頁面進行註冊,有可能這個Dialog會複用,或者改一些樣式(採用Builder設計模式)]
接下來自定義Dialog
