// 键盘状态判断
InputMethodManager imm = (InputMethodManager) PieChartDetailActivity.this.getSystemService(PieChartDetailActivity.this.INPUT_METHOD_SERVICE);
if (imm.hideSoftInputFromWindow(v.getWindowToken(), 0)) {
imm.showSoftInput(v, 0);
Log.d("PieChartDetailActivity", "软键盘已弹出");
//软键盘已弹出
} else {
Log.d("PieChartDetailActivity", "软键盘未弹出");

}
密码框设置
显示内容
editText.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
加密内容
editText.setInputType(0x00000080);
输入框的光标位置移动 需要在子线程中运行
// 子线程调用
Timer timer = new Timer();
timer.schedule(new MyTask(), 1);
// 调用运行更新 方法
private class MyTask extends TimerTask {
@Override
public void run() {
Message message = new Message();
message.what = 1;
mHandler.sendMessage(message);
}
}
// 子线程
private Handler mHandler = new Handler() {
public void handleMessage(Message msg) {
// 更新UI操作
// 移动光标位置
CharSequence text = editTextUserpassword.getText();
if (text instanceof Spannable) {
Spannable spanText = (Spannable) text;
Selection.setSelection(spanText, text.length());
}
}
};
editText 焦点 兼左边图标处理设置 就输入密码 左边的小图标也要跟着变换
nav_up = getResources().getDrawable(R.drawable.password1_green);
nav_up1 = getResources().getDrawable(R.drawable.password1);
nav_up.setBounds(0, 0, nav_up.getMinimumWidth(), nav_up.getMinimumHeight());
nav_up1.setBounds(0, 0, nav_up1.getMinimumWidth(), nav_up1.getMinimumHeight());
editText1.setOnFocusChangeListener(new android.view.View.OnFocusChangeListener() {
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
// 此处为得到焦点时的处理内容
editText1.setBackground(getResources().getDrawable(R.drawable.border_bootm));
editText1.setCompoundDrawables(nav_up, null,null , null);
} else {
// 此处为失去焦点时的处理内容
editText1.setBackground(getResources().getDrawable(R.drawable.border_bootm_gray));
editText1.setCompoundDrawables(nav_up1, null,null , null);
}
}
});
EditText 文字外观设置
android:textAppearance 设置文字外观。
如“?android:attr/textAppearanceLargeInverse
”这里引用的是系统自带的一个外观，？表示系统是否有这种外观，否则使用默认的外观。
可设置的值如下：textAppearanceButton/textAppearanceInverse/textAppearanceLarge/
textAppearanceLargeInverse/textAppearanceMedium/textAppearanceMediumInverse/
textAppearanceSmall/textAppearanceSmallInverse
editText.getPaint().setFlags(Paint. UNDERLINE_TEXT_FLAG ); //下划线
editText.getPaint().setAntiAlias(true);//抗锯齿
editText.getPaint().setFlags(Paint. STRIKE_THRU_TEXT_FLAG); //中划线
editText.setFlags(Paint. STRIKE_THRU_TEXT_FLAG|Paint.ANTI_ALIAS_FLAG); // 设置中划线并加清晰
editText.getPaint().setFlags(0); // 取消设置的的划线
排除特殊字符 和空格之类的东西 只能输入 英文和 中文 EditText
public void setIfSpecialCharacters(final EditText ed) {
//ed.setOnClickListener(this); // 有些要用的
ed.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
String va = ed.getText().toString();
if (va.length() > 0) {
String reg = "[^a-zA-Z\u4E00-\u9FA5]";
if (va.replaceAll(reg, "").length() < va.length()) {
ed.setText(Util.ReString(va));
}
}
System.out.println(Util.ReString(va));
ed.setSelection(ed.getText().length());
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});
}
判断是否有中文字符
/**
* 验证中文
*
* @param chinese 中文字符
* @return 验证成功返回true，验证失败返回false
*/
public static boolean checkChinese(String chinese) {
String regex = "^[\u4E00-\u9FA5]+$";
return Pattern.matches(regex, chinese);
}
EditText 在addTextChangedListener 里面操作 的焦点重复调用问题处理
通过移除焦点和 添加焦点 解决递归操作问题 打比方说要清空掉用户输入的东西 就会有递归的问题了
/**设置空数据 去除焦点！！！！！*/
et_content.removeTextChangedListener(this);
/**收起键盘*/
InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
holder.et_content.setText("");
/**设置空数据后 把焦点加回来 核心代码 */
holder.et_content.addTextChangedListener(this);
Edit重写
et_searchData.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
}
});
只能输入 数字和英文 限制 直接在xml里面写就好了
android:inputType="number"
android:digits="1234567890qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM"
EditText 输入类型
android:inputType="numberDecimal" 输入金额
android:singleLine="true" //禁止输入回车
自动换行
android:inputType="textMultiLine"
EditText 无法编辑
android:focusable="false"
缩回输入法
InputMethodManager m = (InputMethodManager) mContext.getSystemService(Context.INPUT_METHOD_SERVICE);
m.hideSoftInputFromWindow(Et_search.getWindowToken(), 0);//比如EditView
禁止EditText输入特殊字符
/**
* 禁止EditText输入特殊字符
* @param editText
*/
public static void setEditTextInhibitInputSpeChat(EditText editText){
InputFilter filter=new InputFilter() {
@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
String speChat="[`~!@#$%^&*()+=|{}':;',\\[\\].<>/?~！@#￥%……&*（）——+|{}【】‘；：”“’。，、？]";
Pattern pattern = Pattern.compile(speChat);
Matcher matcher = pattern.matcher(source.toString());
if(matcher.find())return "";
else return null;
}
};
editText.setFilters(new InputFilter[]{filter});
}
//监听输入框禁止输入空格
Et_search.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
if (s.toString().contains(" ")) {
String[] str = s.toString().split(" ");
String str1 = "";
for (int i = 0; i < str.length; i++) {
str1 += str[i];
}
Et_search.setText(str1);
Et_search.setSelection(start);
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void afterTextChanged(Editable s) {
}
});
只能输入中文 的EditText
public void setEd(EditText et_chinese){
//输入过滤器可以实现很多效果
InputFilter filter = new InputFilter() {public CharSequence filter(CharSequence source, int start, int end,
Spanned dest, int dstart, int dend) {
for (int i = start; i < end; i++) {
if (!isChinese(source.charAt(i))) {
return "";
}
}
return null;
}
};
et_chinese.setFilters(new InputFilter[]{filter});
//如果想要再实现输入字符数量的限制，可以这么写,如果限制字符数为6，就在LengthFilter中传入参数6
//et_chinese.setFilters(new InputFilter[]{filter, new InputFilter.LengthFilter(6)});
}
/**
* 判定输入汉字，通过Unicode表
*
* @param c
* @return
*/
public boolean isChinese(char c) {
Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
|| ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
|| ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
|| ub == Character.UnicodeBlock.GENERAL_PUNCTUATION
|| ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
|| ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {
return true;
}
return false;
}
在最新手机号码正则
^((13[0-9])|(14[5,7])|(15[0-3,5-9])|(17[0,3,5-8])|(18[0-9])|166|198|199|(147))\\d{8}$
默认不打开输入法 清单文件设置
android:windowSoftInputMode="adjustUnspecified|stateAlwaysHidden"
代码里面执行
在 onCreate切记要倒计时 直接调用不行 应该有更好的写法吧
// 弹出输入框
new Handler().postDelayed(new Runnable(){
public void run() {
InputMethodManager inputManager = (InputMethodManager) getApplication().getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
}
}, 300);
