1. 声明EditText变量，并关联到相应控件上
1 private EditText sellStartTime; 2 private EditText sellEndTime;
1 sellStartTime = (EditText)findViewById(R.id.editSellStartTime); 2 sellEndTime = (EditText)findViewById(R.id.editSellEndTime);
2. 日期选择器函数
1 private DatePickerDialog.OnDateSetListener mDateSetListener = 2 new DatePickerDialog.OnDateSetListener() { 3 public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { 4 mYear = year; 5 String mm; 6 String dd; 7 if(monthOfYear<=9) 8 { 9 mMonth = monthOfYear+1; 10 mm="0"+mMonth; 11 } 12 else{ 13 mMonth = monthOfYear+1; 14 mm=String.valueOf(mMonth); 15 } 16 if(dayOfMonth<=9) 17 { 18 mDay = dayOfMonth; 19 dd="0"+mDay; 20 } 21 else{ 22 mDay = dayOfMonth; 23 dd=String.valueOf(mDay); 24 } 25 mDay = dayOfMonth; 26 if(timeFlag == 0) { 27 sellStartTime.setText(String.valueOf(mYear)+"-"+mm+"-"+dd); 28 }else { 29 sellEndTime.setText(String.valueOf(mYear)+"-"+mm+"-"+dd); 30 } 31 } 32 }; 33 34 protected Dialog onCreateDialog(int id) { 35 switch (id) { 36 case 0: 37 return new DatePickerDialog(this, 38 mDateSetListener, 39 mYear, mMonth, mDay); 40 case 1: 41 return new DatePickerDialog(this, 42 mDateSetListener, 43 mYear, mMonth, mDay); 44 } 45 return null; 46 } 47 48 // 隐藏手机键盘 49 private void hideIM(View edt){ 50 try { 51 InputMethodManager im = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE); 52 IBinder windowToken = edt.getWindowToken(); 53 if(windowToken != null) { 54 im.hideSoftInputFromWindow(windowToken, 0); 55 } 56 } catch (Exception e) { 57 58 } 59 }
3. 注册监听器，当EditText获得焦点时，或者被点击时，打开日期选择器
1 sellStartTime.setOnClickListener(new OnClickListener(){ 2 public void onClick(View v) { 3 timeFlag = 0; 4 showDialog(0); 5 } 6 }); 7 sellEndTime.setOnClickListener(new OnClickListener() { 8 public void onClick(View v) { 9 timeFlag = 1; 10 showDialog(1); 11 } 12 }); 13 sellStartTime.setOnFocusChangeListener(new OnFocusChangeListener() { 14 public void onFocusChange(View v, boolean hasFocus) { 15 if (hasFocus == true) { 16 timeFlag = 0; 17 hideIM(v); 18 showDialog(0); 19 } 20 } 21 }); 22 23 sellEndTime.setOnFocusChangeListener(new OnFocusChangeListener() { 24 public void onFocusChange(View v, boolean hasFocus) { 25 if (hasFocus == true) { 26 timeFlag = 1; 27 hideIM(v); 28 showDialog(1); 29 } 30 } 31 });
4. 在包含EditText的LinearLayout中，添加语句
1 android:focusable="true" android:focusableInTouchMode="true"
这句话，是为了防止EditText自动获取焦点，触发日期选择器。
EditText如何关闭软键盘
方法一：
在AndroidMainfest.xml中选择哪个activity，设置windowSoftInputMode属性为adjustUnspecified|stateHidden
例如：<activity android:name=".Main"
android:label="@string/app_name"
android:windowSoftInputMode="adjustUnspecified|stateHidden"
android:configChanges="orientation|keyboardHidden">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
方法二：
强制隐藏Android输入法窗口
例如：EditText edit=(EditText)findViewById(R.id.edit);
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(edit.getWindowToken(),0);
2.EditText始终不弹出软件键盘
例：EditText edit=(EditText)findViewById(R.id.edit);
edit.setInputType(InputType.TYPE_NULL);
还有一个问题是怎样才能不让实体键盘也输入呢，解决方法
Android用代码实现EditText不可编辑
editText.setFilters(new InputFilter[] { new InputFilter() {
@Override
public CharSequence filter(CharSequence source, int start,
int end, Spanned dest, int dstart, int dend) {
return source.length() < 1 ? dest.subSequence(dstart, dend) : "";
}
}
}); 但是这样连DatePicker的设置也不能显示到EditText里了，改一改
//实现EditText不可编辑
birthEdit.setFilters(new InputFilter[]{new InputFilter(){
@Override
public CharSequence filter(CharSequence source, int start, int end,
Spanned dest, int dstart, int dend) {
showDialog(HmConst.DIALOG_DATEPICKER);//不管按什么键都让DatePicker出现
return source.length() == 1 ? "" : source; //DatePicker的设置还是要让他显示滴
}
}});
我的实验代码，可行
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.register);
birthEdit =(EditText)findViewById(R.id.birthEdit);
makeDateEdit();
}
/**
* 将EditText变成一个日期选择器
*/
public void makeDateEdit(){
//隐藏EditText键盘
birthEdit.setInputType(InputType.TYPE_NULL);
//点击显示DatePickerDialog
birthEdit.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showDialog(HmConst.DIALOG_DATEPICKER);
}
});
//实现EditText不可编辑
birthEdit.setFilters(new InputFilter[]{new InputFilter(){
@Override
public CharSequence filter(CharSequence source, int start, int end,
Spanned dest, int dstart, int dend) {
showDialog(HmConst.DIALOG_DATEPICKER);//不管按什么键都让DatePicker出现
return source.length() == 1 ? "" : source;
}
}});
//屏蔽实体键盘delete键
birthEdit.setOnKeyListener(new OnKeyListener(){
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
if(keyCode == KeyEvent.KEYCODE_DEL) {
showDialog(HmConst.DIALOG_DATEPICKER);//delete键都让DatePicker出现
return true;//返回真就会屏蔽delete键的原效果
}
return false;
}
});
//设置时间选择器的监听器
mDateSetListener = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
mYear = year;
String mm;
String dd;
mMonth = monthOfYear+1; //因为month是从0开始计数的
if(mMonth<=9)
{
mm="0"+mMonth;
}
else{
mm=String.valueOf(mMonth);
}
mDay = dayOfMonth;
if(mDay<=9)
{
dd="0"+mDay;
}
else{
dd=String.valueOf(mDay);
}
mDay = dayOfMonth;
//将选择的时间显示在EditText上
birthEdit.setText(String.valueOf(mYear)+"-"+mm+"-"+dd);
}
};
}
@Override
protected Dialog onCreateDialog(int id) {
// TODO Auto-generated method stub
switch(id){
case HmConst.DIALOG_DATEPICKER:
return new DatePickerDialog(this,mDateSetListener,2010,11,25);
default:
return null;
}
}
