Android带清除按钮、密码可见小眼睛的输入框

相信不少小伙伴在开发登录功能时候，或多或少都会用到输入框清除按钮、密码可见与隐藏小眼睛按钮，我之前也是但写这个功能，但是在找回密码、忘记密码里面还要重新写一次很是麻烦，现在我把它只做了一个自定义控件，可以配置清除按钮、密码可见小眼睛是否显示以及图标，有渐隐渐显和横向移动动画，不知道怎么上传可以直接观看的视频，附上三张效果图，可以点击链接观看视频是否是你想要的效果。

我的这个自带清除、小眼睛的控件，是一个自定义控件，控件名称ClearEditText.class，继承RelativeLayout并有布局引用。在拷贝到项目里面后，使用时候只需要与普通输入框控件一样，进行相关的配置即可，部分属性需要使用自定义属性，具体见代码。

拷贝ClearEditText.class类到自己的项目里，再考拷贝它相关的布局文件、自定义属性、默认图片即可，下面贴出ClearEditText主要代码：

public class ClearEditText extends RelativeLayout { private ImageView ivLeftIcon; private EditText myEdie; private ImageView ivEditClean; private ImageView ivEditEye; private boolean isChecked = true; private Context mContext; private TypedArray mTypedArray; private boolean showClean = true;//清空图标是否显示，true:显示 private boolean showEye = false;//密码可见图标是否显示，true:显示 private int drawableLeft = -1;//是否显示输入框左侧图片 private int drawableEyeOpen = R.drawable.clear_icon_eye_open;//可以看见密码小眼睛样式 private int drawableEyeClose = R.drawable.clear_icon_eye_close;//不可见密码小眼睛样式 private int drawableClean = R.drawable.clear_icon_close;//清除按钮图片 private int cleanPadding = 0;//清除按钮padding边距 private String hintStr; private String textStr; private int mTextColorHint = Color.BLACK; private int mTextColor = Color.BLACK; private int mTextSize = -1; private int mMaxLength = 2000; private int mMaxLines = 1; private int mInputType = 0;//输入类型，就做了不限制、数字、文本密码三种 private boolean isInput = false;//输入1个字符后更改状态为true,保证小眼睛移动一次 private boolean isHideClean = false;//输入字符后，清除了需要小眼睛归为，清除按钮隐藏 private int ivWidth = 45;//关闭按钮的宽度 public ClearEditText(Context context) { super(context); mContext = context; initView(); } public ClearEditText(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); mContext = context; mTypedArray = mContext.obtainStyledAttributes(attrs, R.styleable.myEditText); initView(); } public ClearEditText(Context context, AttributeSet attrs) { super(context, attrs); mContext = context; mTypedArray = mContext.obtainStyledAttributes(attrs, R.styleable.myEditText); showClean = mTypedArray.getBoolean(R.styleable.myEditText_showClean, showClean); drawableClean = mTypedArray.getResourceId(R.styleable.myEditText_drawableClean, drawableClean); cleanPadding = mTypedArray.getDimensionPixelSize(R.styleable.myEditText_cleanPadding, cleanPadding); showEye = mTypedArray.getBoolean(R.styleable.myEditText_showEye, showEye); drawableLeft = mTypedArray.getResourceId(R.styleable.myEditText_drawableLeft, -1); drawableEyeClose = mTypedArray.getResourceId(R.styleable.myEditText_drawableEyeClose, drawableEyeClose); drawableEyeOpen = mTypedArray.getResourceId(R.styleable.myEditText_drawableEyeOpen, drawableEyeOpen); hintStr = mTypedArray.getString(R.styleable.myEditText_hint); textStr = mTypedArray.getString(R.styleable.myEditText_text); mTextColorHint = mTypedArray.getColor(R.styleable.myEditText_textColorHint, mTextColorHint); mTextColor = mTypedArray.getColor(R.styleable.myEditText_textColor, mTextColor); mTextSize = mTypedArray.getDimensionPixelSize(R.styleable.myEditText_textSize, mTextSize); mMaxLength = mTypedArray.getInteger(R.styleable.myEditText_maxLength, mMaxLength); mMaxLines = mTypedArray.getDimensionPixelSize(R.styleable.myEditText_maxLines, mMaxLines); mInputType = mTypedArray.getInteger(R.styleable.myEditText_inputType, mInputType); mTypedArray.recycle(); initView(); } // 初始化视图 private void initView() { View view = View.inflate(getContext(), R.layout.clear_layout_view, null); ivLeftIcon = (ImageView) view.findViewById(R.id.iv_edit_left_icon); myEdie = (EditText) view.findViewById(R.id.view_edit_show); ivEditClean = (ImageView) view.findViewById(R.id.iv_edit_clean); ivEditEye = (ImageView) view.findViewById(R.id.iv_edit_eye); myEdie.setHint(hintStr); myEdie.setHintTextColor(mTextColorHint); myEdie.setText(textStr); myEdie.setTextColor(mTextColor); myEdie.setMaxLines(mMaxLines); myEdie.setFilters(new InputFilter[]{new InputFilter.LengthFilter(mMaxLength)}); if (mTextSize != -1) { myEdie.setTextSize(TypedValue.COMPLEX_UNIT_PX, mTextSize); } else { myEdie.setTextSize(15); } if (mInputType == 1) { myEdie.setInputType(InputType.TYPE_CLASS_NUMBER); } else if (mInputType == 2) { myEdie.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD | InputType.TYPE_CLASS_TEXT); } else { myEdie.setInputType(InputType.TYPE_NUMBER_VARIATION_NORMAL | InputType.TYPE_CLASS_TEXT); } if (showEye) { myEdie.setTransformationMethod(new AsteriskPasswordTransformationMethod()); } if (showClean && showEye) { int left = myEdie.getPaddingLeft(); int top = myEdie.getPaddingTop(); int bottom = myEdie.getPaddingBottom(); myEdie.setPadding(left, top, Utils.dp2px(mContext, 90), bottom); } else if (!showClean && !showEye) { int left = myEdie.getPaddingLeft(); int top = myEdie.getPaddingTop(); int right = myEdie.getPaddingRight(); int bottom = myEdie.getPaddingBottom(); myEdie.setPadding(left, top, right, bottom); } else { int left = myEdie.getPaddingLeft(); int top = myEdie.getPaddingTop(); int bottom = myEdie.getPaddingBottom(); myEdie.setPadding(left, top, Utils.dp2px(mContext, 45), bottom); } myEdie.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) { if (s.length() > 0) { isHideClean = false; } } @Override public void afterTextChanged(Editable s) { if (s.length() > 0 && !isInput) {//输入字符大于0且只有一个字符时候显示清除按钮动画，小眼睛移动出位置给清除按钮使用 showEditClean(); moveEditEye(); isInput = true; } else if (s.length() == 0) {//无字符小眼睛归位 UndoEditEye(); } if (s.length() == 0 & !isHideClean) { hideEditClean(); isHideClean = true; isInput = false; } if (onEditInputListener != null) { onEditInputListener.input(getText()); } } }); setEditClean(showClean); ivEditClean.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { myEdie.setText(''); } }); ivEditClean.setImageResource(drawableClean); ivEditClean.setPadding(cleanPadding, cleanPadding, cleanPadding, cleanPadding); setEditEye(showEye); ivEditEye.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (isChecked) { // 输入一个对用户可见的密码 myEdie.setTransformationMethod(HideReturnsTransformationMethod.getInstance()); myEdie.setSelection(getText().length()); ivEditEye.setImageResource(drawableEyeOpen); isChecked = false; } else { // 输入一个对用户不可见的密码 myEdie.setTransformationMethod(new AsteriskPasswordTransformationMethod()); myEdie.setSelection(getText().length()); ivEditEye.setImageResource(drawableEyeClose); isChecked = true; } } }); if (drawableLeft != -1) { ivLeftIcon.setVisibility(View.VISIBLE); ivLeftIcon.setImageResource(drawableLeft); } else { ivLeftIcon.setVisibility(View.GONE); } view.setLayoutParams(new LayoutParams(ViewPager.LayoutParams.MATCH_PARENT, ViewPager.LayoutParams.WRAP_CONTENT)); addView(view); } //密码不可见时候，使用*替换密码 public class AsteriskPasswordTransformationMethod extends PasswordTransformationMethod { @Override public CharSequence getTransformation(CharSequence source, View view) { return new PasswordCharSequence(source); } private class PasswordCharSequence implements CharSequence { private CharSequence mSource; public PasswordCharSequence(CharSequence source) { mSource = source; // Store char sequence } public char charAt(int index) { return ’*’; // This is the important part } public int length() { return mSource.length(); // Return default } public CharSequence subSequence(int start, int end) { return mSource.subSequence(start, end); // Return default } } } public String getText() { return myEdie.getText().toString().trim(); } public void setText(String text) { myEdie.setText(text); } //代码设置是否显示清除按钮 public void setEditClean(boolean isCanClose) { showClean = isCanClose; } //代码设置是否显示小眼睛 public void setEditEye(boolean isCanSee) { showEye = isCanSee; if (showEye == true) { ivEditEye.setVisibility(View.VISIBLE); } else { ivEditEye.setVisibility(View.GONE); } } private void showEditClean() { if (showClean == true) { AnimationUtils.showAndHiddenCenterAnimation(ivEditClean, AnimationUtils.AnimationState.STATE_SHOW, 500); } } private void hideEditClean() { if (showClean == true) { AnimationUtils.showAndHiddenCenterAnimation(ivEditClean, AnimationUtils.AnimationState.STATE_HIDDEN, 500); } } private void moveEditEye() { if (showEye) { ObjectAnimator.ofFloat(ivEditEye, 'translationX', -Utils.dp2px(mContext, ivWidth)).setDuration(500).start();

} //输入监听 public interface OnEditInputListener { void input(String content); }}2.使用示例

下面是在xml布局时候，如何使用ClearEditText的示例，部分自定义属性使用xmlns:app='http://schemas.android.com/apk/res-auto'引用调用。app:showEye属性true-显示小眼睛，false-关闭小眼睛。

<com.huaweixia.clear.ClearEditText android: android:layout_width='0dp' android:layout_height='45dp' android:layout_marginTop='30dp' android:background='@drawable/line_bg_white_only_bottom_d8' android:paddingLeft='10dp' app:hint='请输入密码' app:layout_constraintLeft_toLeftOf='@id/et_login_number' app:layout_constraintRight_toRightOf='@id/et_login_number' app:layout_constraintTop_toBottomOf='@id/et_login_number' app:showEye='true' app:textColor='@color/tv_black_333333' app:textColorHint='@color/tv_gray_999999' app:textSize='15sp' />总结

一开始我之前自己用的自带清空、密码可见的自定义输入框，是没有清除按钮显示，密码可见按钮移动动效，清除按钮显示比较僵硬，在清除按钮隐藏时候小眼睛按钮后面有一定空白，显示看着比较别扭，加了动效后视觉上感觉更加顺畅，希望对部分需要的小伙伴有空，下面附上 下载demo的链接 地址，有需要可以下载看看。
