Android功能引导界面实现 – Android开发中文站

一.界面实现：

借鉴了别人的实例，然后记录下引导界面的实现，总体来说实现不算困难，前提是要有个美工帮你做这些引导图片（找了张图片凑合用吧）：

主界面：

1 2 3 4 5 6 7 8 9

public class MainActivity extends PromptActivity {     //activity的生命周期     public void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.activity_main);          setGuideResId(R.drawable.prompt2);// 添加引导页     } }

引导界面：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53

public class PromptActivity extends Activity {      private int guideResourceId = 0;// 引导页图片资源id      private PromptSharedPreferences psp;      @Override      protected void onStart() {           super.onStart();           addGuideImage();// 添加引导页      }      //显示引导图片      public void addGuideImage() {           psp = new PromptSharedPreferences();           View view = getWindow().getDecorView().findViewById(R.id.my_content_view);// 查找通过setContentView上的根布局           if (view == null)                return;           if (psp.takeSharedPreferences(this)) {                // 有过功能引导，就跳出                return;           }           ViewParent viewParent = view.getParent();           if (viewParent instanceof FrameLayout) {                 final FrameLayout frameLayout = (FrameLayout) viewParent;                 if (guideResourceId != 0) {                      // 设置了引导图片                      final ImageView guideImage = new ImageView(this);                      FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(                      ViewGroup.LayoutParams.FILL_PARENT,                      ViewGroup.LayoutParams.FILL_PARENT);                      guideImage.setLayoutParams(params);                      guideImage.setScaleType(ScaleType.FIT_XY);                      guideImage.setImageResource(guideResourceId);                      guideImage.setOnClickListener(new View.OnClickListener() {                            @Override                            public void onClick(View v) {                                 //删除引导图片                                 frameLayout.removeView(guideImage);                                 //保存记录                                 psp.saveSharedPreferences(PromptActivity.this, "启动了");                            }                      });                      frameLayout.addView(guideImage);// 添加引导图片                }          }     }     //获得图片id     protected void setGuideResId(int resId) {          this.guideResourceId = resId;     } }

布局:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

<LinearLayout       android:orientation="vertical"       android:layout_width="fill_parent"       android:layout_height="fill_parent"       android:id="@id/my_content_view" >       <TextView             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:layout_marginTop="58dp"             android:layout_marginLeft="150dp"             android:text="哈哈哈哈" />      <TextView             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:layout_marginTop="58dp"             android:layout_marginLeft="275dp"             android:text="哈" /> </LinearLayout>

本地文件：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

public class PromptSharedPreferences {      private SharedPreferences sp;      // 保存      public void saveSharedPreferences(Context context, String save) {           sp = context.getSharedPreferences("prompt", context.MODE_PRIVATE);           Editor editor = sp.edit();           editor.putString("state", save);           editor.commit();// 保存新数据      }      // 取出      public boolean takeSharedPreferences(Context context) {           String str = "";           sp = context.getSharedPreferences("prompt", context.MODE_PRIVATE);           str = sp.getString("state", "");           if (str.equals("")) {                 return false;           }else{                 return true;           }      } }

添加values/ids.xml:

1 2 3 4 5

<?xml version="1.0" encoding="utf-8"?>      <resources>           <item type="id" name="my_content_view"></item>      </resources> </xml>
