问题描述
我有code一的EditText，但我无法弄清楚如何使同一code的第二EDITTEXT盒，位于同一页上。这是我的code：
包tryone.now.forfreenow;
进口android.app.Activity;
进口android.content.Shared preferences;
进口android.os.Bundle;
进口android.widget.EditText;
进口android.widget.TextView;
公共类记事本扩展活动
{
@覆盖
保护无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.main）;
编辑框=（EditText上）findViewById（R.id.editText1）;
}
保护无效onResume（）{
super.onResume（）;
共享preferences preFS = GET preferences（0）;
字符串restoredText = prefs.getString（文字，NULL）;
如果（restoredText！= NULL）{
editBox.setText（restoredText，TextView.BufferType.EDITABLE）;
INT selectionStart = prefs.getInt（选择开始，-1）;
INT选定结束= prefs.getInt（选择高端，-1）;
如果（selectionStart = -1＆安培;！＆安培;！选定结束= -1）{
editBox.setSelection（selectionStart，选定结束）;
}
}
}
保护无效的onPause（）{
super.onPause（）;
共享preferences.Editor编辑= GET preferences（0）.edit（）;
editor.putString（文本，editBox.getText（）的toString（））;
editor.putInt（选择开始，editBox.getSelectionStart（））;
editor.putInt（选择高端，editBox.getSelectionEnd（））;
editor.commit（）;
}
私人的EditText编辑框;
}

INT selectionEnd2 = prefs2.getInt（选择 - END2，-1）;
如果（！selectionStart2 = -1＆功放;＆安培; selectionEnd2！= -1）
{
editBox2.setSelection（selectionStart2，selectionEnd2）;

I have code for one EditText, but I can not figure out how to make same code for second editText Box, that is located on the same page. Here is my code:
package tryone.now.forfreenow;
import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.TextView;
public class notepad extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
editBox =(EditText)findViewById(R.id.editText1);
}
protected void onResume() {
super.onResume();
SharedPreferences prefs = getPreferences(0);
String restoredText = prefs.getString("text", null);
if (restoredText != null) {
editBox.setText(restoredText, TextView.BufferType.EDITABLE);
int selectionStart = prefs.getInt("selection-start", -1);
int selectionEnd = prefs.getInt("selection-end", -1);
if (selectionStart != -1 && selectionEnd != -1) {
editBox.setSelection(selectionStart, selectionEnd);
}
}
}
protected void onPause() {
super.onPause();
SharedPreferences.Editor editor = getPreferences(0).edit();
editor.putString("text", editBox.getText().toString());
editor.putInt("selection-start", editBox.getSelectionStart());
editor.putInt("selection-end", editBox.getSelectionEnd());
editor.commit();
}
private EditText editBox;
}
解决方案
I am answering my own question.It works 100% to save state on two editText boxes.
package tryone.now.forfreenow;
import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.TextView;
public class notepad extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
editBox = (EditText) findViewById(R.id.editText1);
editBox2 = (EditText) findViewById(R.id.editText2);
}
protected void onResume() {
super.onResume();
SharedPreferences prefs = getPreferences(0);
String restoredText = prefs.getString("text", null);
if (restoredText != null)
{
editBox.setText(restoredText, TextView.BufferType.EDITABLE);
int selectionStart = prefs.getInt("selection-start", -1);
int selectionEnd = prefs.getInt("selection-end", -1);
if (selectionStart != -1 && selectionEnd != -1)
{
editBox.setSelection(selectionStart, selectionEnd);
}
SharedPreferences prefs2 = getPreferences(1);
String restoredText2 = prefs2.getString("text2", null);
if (restoredText2 != null)
{
editBox2.setText(restoredText2, TextView.BufferType.EDITABLE);
int selectionStart2 = prefs2.getInt("selection-start2", -1);
int selectionEnd2 = prefs2.getInt("selection-end2", -1);
if (selectionStart2 != -1 && selectionEnd2 != -1)
{
editBox2.setSelection(selectionStart2, selectionEnd2);
}
}
}
}
protected void onPause() {
super.onPause();
SharedPreferences.Editor editor = getPreferences(0).edit();
editor.putString("text", editBox.getText().toString());
editor.putInt("selection-start", editBox.getSelectionStart());
editor.putInt("selection-end", editBox.getSelectionEnd());
editor.commit();
SharedPreferences.Editor editor2 = getPreferences(1).edit();
editor2.putString("text2", editBox2.getText().toString());
editor2.putInt("selection-start2", editBox2.getSelectionStart());
editor2.putInt("selection-end2", editBox2.getSelectionEnd());
editor2.commit();
}
private EditText editBox;
private EditText editBox2;
}
