我有一个包含两个编辑文本字段的搜索活动.我喜欢编辑文本点击日期选择器对话框来显示.但是,当我单击编辑文本时,首先显示键盘,然后在第二次单击后显示日期选择器对话框.有人能帮帮我吗？
这是活动代码
package com.example.firstdemoapp.activities;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;
import com.example.firstdemoapp.R;
import com.example.firstdemoapp.model.StatusDK;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.Spinner;
public class SearchingTaxActivity extends Activity implements OnClickListener,DatePickerDialog.OnDateSetListener,OnItemSelectedListener {
private Calendar calendarFrom;
private Calendar calendarTo;
private String myFormat;
private SimpleDateFormat sdf;
private EditText dateFrom;
private EditText dateTo;
private EditText activeEditText;
private Calendar activeCalendar;
private Spinner spinnerStatusDK;
private ArrayAdapter spinnerArrayAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_tax);
calendarFrom = Calendar.getInstance();
calendarTo = Calendar.getInstance();
myFormat="dd/MM/yyyy";
sdf = new SimpleDateFormat(myFormat,Locale.US);
dateFrom = (EditText) findViewById(R.id.dateFrom);
dateTo = (EditText) findViewById(R.id.dateTo);
spinnerStatusDK=(Spinner)findViewById(R.id.spinnerStatusDK);
spinnerArrayAdapter = new ArrayAdapter(this,android.R.layout.simple_spinner_item,new StatusDK[] {
new StatusDK( 0,"0" ),new StatusDK( 1,"1" ),new StatusDK( 2,"2" ),});
spinnerStatusDK.setAdapter(spinnerArrayAdapter);
spinnerStatusDK.setOnItemSelectedListener(this);
dateFrom.setOnClickListener(this);
dateTo.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v == dateFrom) {
activeCalendar = calendarFrom;
activeEditText = dateFrom;
} else if (v == dateTo) {
activeCalendar = calendarTo;
activeEditText = dateTo;
}
new DatePickerDialog(SearchingTaxActivity.this,this,activeCalendar.get(Calendar.YEAR),activeCalendar.get(Calendar.MONTH),activeCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
@Override
public void onDateSet(DatePicker view,int year,int monthOfYear,int dayOfMonth) {
// TODO Auto-generated method stub
activeCalendar.set(Calendar.YEAR,year);
activeCalendar.set(Calendar.MONTH,monthOfYear);
activeCalendar.set(Calendar.DAY_OF_MONTH,dayOfMonth);
if (activeEditText != null) {
activeEditText.setText(sdf.format(activeCalendar.getTime()));
}
}
@Override
public void onItemSelected(AdapterView<?> arg0,View arg1,int arg2,long arg3) {
// TODO Auto-generated method stub
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
并且活动的布局是：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="${relativePackage}.${activityClass}" >
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/dateFromTextView"
/>
<EditText
android:id="@+id/dateFrom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="@string/edit_datefrom"
/>
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/dateToTextView"
/>
<EditText
android:id="@+id/dateTo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="@string/edit_dateto"
/>
<Spinner
android:id="@+id/spinnerStatusDK"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
