功能：
1.自定义长度，改一个数字就可改变密码输入框长度
2.可使用虚拟键盘输入也可以使用实体键盘输入
3.可以直接在外部界面输入，也可以在弹出的输入界面输入。
1.自定义长度，改一个数字就可改变密码输入框长度
使用设置后再追加的方式。我的做法是用一个自定义布局封装一下。
public class PayPwdLayout extends LinearLayout
public PayPwdLayout(Context context) {
super(context);
}
public PayPwdLayout(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
}
public PayPwdLayout(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public PayPwdLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
public void setPwdLen(int len){
if(len <=0){
return;
}
removeAllViews();
for (int i = 0; i < len; i++) {
TextView tv = new TextView(getContext());
tv.setPadding(50, 50, 50, 50);
tv.setText("");
tv.setGravity(Gravity.CENTER);
tv.setBackgroundDrawable(getResources().getDrawable(R.drawable.bg_card));
addView(tv);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) tv.getLayoutParams();
params.height = LinearLayout.LayoutParams.WRAP_CONTENT;
params.width = 0;
params.weight = 1;
tv.setLayoutParams(params);
}
initEditText();
}
private void initEditText() {
EditText editText = new EditText(getContext());
editText.setBackgroundColor(0);
editText.setInputType(InputType.TYPE_CLASS_NUMBER);
addView(editText);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) editText.getLayoutParams();
params.height = 1;
params.width = 1;
editText.setLayoutParams(params);
editText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
LinearLayout linear_pwd = (LinearLayout) findViewById(R.id.linear_pwd);
if (s.length() == linear_pwd.getChildCount()-1) {
hideKeyboard();
if(mOnCheckPwdListener !=null){
mOnCheckPwdListener.check(s.toString());
}
}
for (int i = 0; i < s.length(); i++) {//●
TextView tv = (TextView) linear_pwd.getChildAt(i);
tv.setText("●");
}
for (int j = s.length(); j < linear_pwd.getChildCount()-1; j++) {
TextView tv = (TextView) linear_pwd.getChildAt(j);
tv.setText("");
}
}
});
}
}
布局里面就把此布局设为：
com.dyy.yonxin.library2.test.paypwd.PayPwdLayout
android:id="@+id/linear_pwd"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:background="@drawable/bg_card"
android:orientation="horizontal"/>
然后，在java代码中，使用如下写法：
final int PWD_LEN = 5;//此处设置密码长度
PayPwdLayout layout = (PayPwdLayout)findViewById(R.id.linear_pwd);
layout.setPwdLen(PWD_LEN);
可以看到，自定义布局时有个EditText，但是大小1px*1px，几乎不可见。这里是因为，如果隐藏EditText，则EditText会屏蔽输入事件，文本长度变化不会被监听。我的设计思路是，在EditText进行输入时，同步显示上方密码的个数，实际内容则是根据EditText内容进行获取的。此时，会有两种输入方式，虚拟键盘和实体键盘。
虚拟键盘输入和实体键盘输入
虚拟键盘输入，需要弹出键盘并让EditText获取焦点：
/**
* 虚拟键盘方式输入
*/
public void showKeyboardInput(){
if(getChildCount()>0 && getChildAt(getChildCount()-1) instanceof EditText){
EditText editText = (EditText) getChildAt(getChildCount()-1);
editText.requestFocus();
showKeyboard();
}
}
实体键盘要考虑到可能出现的功能，基本功能有：设置文本，追加文本，回退一格，清除全部
/**
* 实体键盘输入追加
* @param
public void appendText(String text){
if(getChildCount()>0 && getChildAt(getChildCount()-1) instanceof EditText){
EditText editText = (EditText) getChildAt(getChildCount()-1);
String beforeTxt = editText.getText().toString();
if(beforeTxt.length()+text.length() <= getChildCount()-1)
editText.setText(editText.getText().toString()+text);
}
}
public void delLastText(){
if(getChildCount()>0 && getChildAt(getChildCount()-1) instanceof EditText){
EditText editText = (EditText) getChildAt(getChildCount()-1);
String beforeText = editText.getText().toString();
if(beforeText.length()>0)
editText.setText(beforeText.substring(0,beforeText.length()-1));
}
}
/**
* 强制设置内容
* @param
public void setText(String text){
if(getChildCount()>0 && getChildAt(getChildCount()-1) instanceof EditText){
EditText editText = (EditText) getChildAt(getChildCount()-1);
editText.setText(text);
}
}
public void clear(){
if(getChildCount()>0 && getChildAt(getChildCount()-1) instanceof EditText){
EditText editText = (EditText) getChildAt(getChildCount()-1);
editText.setText("");
}
}
全部用法：
自定义控件：
