安卓软件第一次打开时引导界面以及打开后停留界面

最近在找一个功能，能够在第一次打开软件的时候有一个引导的界面，然后在每次进入软件后都会有一个停留的界面，语言形容的不怎么清楚，上效果。。。。。

以上为效果图，接下来我来说一下大概的实现的方法

首先，MainActivity.java

package com.jaycee.appguide;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
boolean mFirst = isFirstEnter(MainActivity.this,MainActivity.this.getClass().getName());
if(mFirst)
//
mHandler.sendEmptyMessageDelayed(SWITCH_GUIDACTIVITY,5000);
mHandler.sendEmptyMessage(SWITCH_GUIDACTIVITY);
//
else
//
mHandler.sendEmptyMessageDelayed(SWITCH_MAINACTIVITY,5000);
//
mHandler.sendEmptyMessage(SWITCH_MAINACTIVITY);
}
private static final String SHAREDPREFERENCES_NAME = "my_pref";
private static final String KEY_GUIDE_ACTIVITY = "guide_activity";
@SuppressLint("WorldReadableFiles")
@SuppressWarnings("deprecation")
private boolean isFirstEnter(Context context,String className){
if(context==null || className==null||"".equalsIgnoreCase(className))return false;
String mResultStr = context.getSharedPreferences(SHAREDPREFERENCES_NAME, Context.MODE_WORLD_READABLE)
.getString(KEY_GUIDE_ACTIVITY, "");
if(mResultStr.equalsIgnoreCase("false"))
return false;
else
return true;
}
private final static int SWITCH_MAINACTIVITY = 1000;
private final static int SWITCH_GUIDACTIVITY = 1001;
@SuppressLint("HandlerLeak")
public Handler mHandler = new Handler(){
public void handleMessage(Message msg) {
switch(msg.what){
case SWITCH_MAINACTIVITY:
Intent mIntent = new Intent();
mIntent.setClass(MainActivity.this, MainActivity.class);
MainActivity.this.startActivity(mIntent);
MainActivity.this.finish();
break;
case SWITCH_GUIDACTIVITY:
mIntent = new Intent();
mIntent.setClass(MainActivity.this, GuideActivity.class);
MainActivity.this.startActivity(mIntent);
MainActivity.this.finish();
break;
}
super.handleMessage(msg);
}
};
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
</RelativeLayout>

然后为GuideActivity.java,其功能为实现页面的引导，

package com.jaycee.appguide;
import android.app.Activity;
import android.os.Bundle;
import java.util.ArrayList;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Parcelable;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.ImageView;
public class GuideActivity extends Activity {
private ViewPager viewPager;
private ArrayList<View> pageViews;
private ImageView imageView;
private ImageView[] imageViews;
private ViewGroup viewPics;
private ViewGroup viewPoints;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
LayoutInflater inflater = getLayoutInflater();
pageViews = new ArrayList<View>();
pageViews.add(inflater.inflate(R.layout.viewpager_page1, null));
pageViews.add(inflater.inflate(R.layout.viewpager_page2, null));
pageViews.add(inflater.inflate(R.layout.viewpager_page3, null));
imageViews = new ImageView[pageViews.size()];
viewPics = (ViewGroup) inflater.inflate(R.layout.activity_guide, null);
viewPoints = (ViewGroup) viewPics.findViewById(R.id.viewGroup);
viewPager = (ViewPager) viewPics.findViewById(R.id.guidePages);
for(int i=0;i<pageViews.size();i++){
imageView = new ImageView(GuideActivity.this);
imageView.setLayoutParams(new LayoutParams(20,20));
imageView.setPadding(20, 0, 20, 0);
imageViews[i] = imageView;
if(i == 0){
imageViews[i].setBackgroundResource(R.drawable.page_indicator_focused);
}else{
imageViews[i].setBackgroundResource(R.drawable.page_indicator);
}
viewPoints.addView(imageViews[i]);
}
setContentView(viewPics);
viewPager.setAdapter(new GuidePageAdapter());
viewPager.setOnPageChangeListener(new GuidePageChangeListener());
}
private Button.OnClickListener
Button_OnClickListener = new Button.OnClickListener() {
public void onClick(View v) {
setGuided();
Intent mIntent = new Intent();
mIntent.setClass(GuideActivity.this, WelcomeActivity.class);
GuideActivity.this.startActivity(mIntent);
GuideActivity.this.finish();
}
};
private static final String SHAREDPREFERENCES_NAME = "my_pref";
private static final String KEY_GUIDE_ACTIVITY = "guide_activity";
private void setGuided(){
SharedPreferences settings = getSharedPreferences(SHAREDPREFERENCES_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString(KEY_GUIDE_ACTIVITY, "false");
editor.commit();
}
class GuidePageAdapter extends PagerAdapter{
@Override
public void destroyItem(View v, int position, Object arg2) {
// TODO Auto-generated method stub
((ViewPager)v).removeView(pageViews.get(position));
}
@Override
public void finishUpdate(View arg0) {
// TODO Auto-generated method stub
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return pageViews.size();
}
@Override
public Object instantiateItem(View v, int position) {
// TODO Auto-generated method stub
((ViewPager) v).addView(pageViews.get(position));
if (position == 2) {
Button btn = (Button) v.findViewById(R.id.btn_close_guide);
btn.setOnClickListener(Button_OnClickListener);
}
return pageViews.get(position);
}
@Override
public boolean isViewFromObject(View v, Object arg1) {
// TODO Auto-generated method stub
return v == arg1;
}
@Override
public void startUpdate(View arg0) {
// TODO Auto-generated method stub
}
@Override
public int getItemPosition(Object object) {
// TODO Auto-generated method stub
return super.getItemPosition(object);
}
@Override
public void restoreState(Parcelable arg0, ClassLoader arg1) {
// TODO Auto-generated method stub
}
@Override
public Parcelable saveState() {
// TODO Auto-generated method stub
return null;
}
}
class GuidePageChangeListener implements OnPageChangeListener{
@Override
public void onPageScrollStateChanged(int arg0) {
// TODO Auto-generated method stub
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
@Override
public void onPageSelected(int position) {
// TODO Auto-generated method stub
for(int i=0;i<imageViews.length;i++){
imageViews[position].setBackgroundResource(R.drawable.page_indicator_focused);
if(position !=i){
imageViews[i].setBackgroundResource(R.drawable.page_indicator);
}
}
}
}
}

</LinearLayout>

接下来的是在每次打开软件的时候，都会有一个停留的界面。

package com.jaycee.appguide;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.Window;
import android.view.WindowManager;
public class WelcomeActivity extends Activity {
private final long SPLASH_LENGTH = 4000;
Handler handler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_welcome);
handler.postDelayed(new Runnable(){
public void run(){
Intent intent = new Intent(WelcomeActivity.this,MainActivity.class);
startActivity(intent);
finish();
}
},SPLASH_LENGTH);
}
}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/welcome"
tools:context="com.example.phonec.WelcomeActivity" >
</LinearLayout>
