来吧 先看效果
需求是输入一位后 将其设置为 也就是加密展示,并将焦点自动转移到下一个框中 当输入至最后一个框时 执行一定逻辑*
原理: 我们写一个recyclerView 并在recyclerView上面放一个EditText ,这里要注意: 要让EditText覆盖recyclerView ,当我们进行输入时 ,时刻监听EditText内容变化, 一有变化时 ,将当前输入的字符设置给recyclerView的适配器 , 刷新就好
在此 我将这个逻辑代码写成了自定义属性格式 ,扩展性比较高, 使用的话也是非常简单 ,一起来看下吧!

属性如下:
<declare-styleable name="CustomEditText">
//输入是否明文显示
<attr name="ce_show_encryption_Text" format="boolean" />
//框的数量
<attr name="ce_Num" format="integer" />
//当前输入的框是否有加粗效果
<attr name="ce_sel_show_frame" format="boolean" />
//当输入至最后一位时 ,是否执行逻辑 比如调接口等等
<attr name="ce_input_ok_jump" format="boolean" />
</declare-styleable>
框的背景样式布局 默认为此样式布局 如果需要更改 则替换布局即可
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="60dp">
<TextView
android:id="@+id/itemEdit"
android:layout_width="50dp"
android:layout_height="match_parent"
android:background="@drawable/input_default_back_view"
android:gravity="center"
android:textColor="#000000"
android:textSize="24sp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
具体用法: 在activity中:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".DemoActivity">
<com.example.text_1.utils.CustomEditText
android:id="@+id/ce_input"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:ce_sel_show_frame="false"
app:ce_Num="4"
app:ce_show_encryption_Text="true"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
此外如果设置了加粗边框 则需要在代码中动态设置背景样式 以数组格式进行设置 下标0为当前存在焦点的样式 1为失去焦点的样式 不可以多传或少传 数组长度只能为2
加粗边框/不加粗xml如下:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:width="2dp"
android:color="@color/black_tran30" />
<corners android:radius="3dp" />
</shape>
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:width="0.5dp"
android:color="#A3A3A3" />
<corners android:radius="3dp" />
</shape>
package com.example.text_1;
import com.example.text_1.utils.BaseActivity;
import com.example.text_1.utils.CustomEditText;
import java.util.ArrayList;
import java.util.List;
import butterknife.BindView;
public class DemoActivity extends BaseActivity {
@BindView(R.id.ce_input)
CustomEditText ceInput;
@Override
public void initView() {
ceInput.setInput_backList(inputListData());
ceInput.setEndJumpCLick(s -> showToast(s));
}
/**
* 背景框
*
* @return 返回集合
*/
private List<Integer> inputListData() {
ArrayList<Integer> integers = new ArrayList<>();
integers.add(R.drawable.edit_shape_focus);
integers.add(R.drawable.edit_shape_not_focus);
return integers;
}
@Override
public int getLayout() {
return R.layout.activity_demo;
}
}
最终 效果如下:
希望对你有所帮助
