EditTextPreference

Further work on last exercise "Preferences and SharedPreferences", a EditTextPreference will be added here.



Modify mypreference.xml too add a EditTextPreference

<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
<CheckBoxPreference
android:key="checkboxvalue"
android:title="Checkbox"
android:defaultValue="true"
android:summary="CheckBoxPreference" />
<EditTextPreference
android:key="edittexvalue"
android:title="EditText"
android:summary="EditTextPreference" />
</PreferenceScreen>

Modify main.xml to have TextView for the EditTextPreference

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
<TextView 
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="@string/hello"
   />
<Button
   android:id="@+id/setpreference"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="Set Preference"
   />
<TextView
   android:id="@+id/checkboxstatus"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   />
<TextView
   android:id="@+id/edittextstatus"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   />
</LinearLayout>

Modify AndroidPreference.java

package com.exercise.AndroidPreference;

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class AndroidPreference extends Activity {

TextView checkBoxStatus, editTextStatus;

   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

       Button buttonSetPreference = (Button)findViewById(R.id.setpreference);
       checkBoxStatus = (TextView)findViewById(R.id.checkboxstatus);
       editTextStatus = (TextView)findViewById(R.id.edittextstatus);
      
       buttonSetPreference.setOnClickListener(new Button.OnClickListener(){

  @Override
  public void onClick(View arg0) {
   // TODO Auto-generated method stub
   startActivity(new Intent(AndroidPreference.this, SetPreference.class));
  }});
   }

@Override
protected void onResume() {
 // TODO Auto-generated method stub
 super.onResume();
 Toast.makeText(this, "onResume", Toast.LENGTH_LONG).show();

 SharedPreferences myPreference=PreferenceManager.getDefaultSharedPreferences(this);
 checkBoxStatus.setText("CheckBox Status: " + myPreference.getBoolean("checkboxvalue", true));
 editTextStatus.setText("EditText Status: " + myPreference.getString("edittexvalue", ""));
}
}
