安卓軟體第一次開啟時引導介面以及開啟後停留介面
阿新 • • 發佈：2019-01-28
最近在找一個功能，能夠在第一次開啟軟體的時候有一個引導的介面，然後在每次進入軟體後都會有一個停留的介面，語言形容的不怎麼清楚，上效果。。。。。
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; } }
其相對應的佈局檔案為：
<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>
然後為GuideActivity.java,其功能為實現頁面的引導，
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); } } } } }
相對應的佈局為：
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+id/guidePages"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:id="@+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/viewGroup"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="40dp"
android:gravity="center_horizontal"
android:orientation="horizontal" >
</LinearLayout>
</RelativeLayout>
</LinearLayout>
</FrameLayout><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/jiemian_1"
android:orientation="vertical">
<!--<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:text="哈哈，這是引導的第一個頁面"
/> -->
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/jiemian_2"
android:orientation="vertical">
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/jiemian_3"
android:gravity="center">
<Button
android:id="@+id/btn_close_guide"
android:layout_width="100dp"
android:layout_height="40dp"
android:background="#D1D1D1"
android:text="開始體驗"
android:layout_marginTop="400dp"
android:textSize="18sp"/>
</LinearLayout>
以上的就是在第一次開啟軟體的時候所出現的引導的介面，
接下來的是在每次開啟軟體的時候，都會有一個停留的介面。
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);
}
}
佈局：
<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>
好的，以上的基本就是這樣了
