TabLayout+ViewPager+Fragment+NDK+WebView+动画+自定义View+AIDL+xUtils+Fresco
一, 导入依赖 和 jar 包
compile 'com.jakewharton:butterknife:8.8.1' compile 'com.jakewharton:butterknife-compiler:8.8.1' compile 'com.android.support:recyclerview-v7:25.3.1' compile 'com.facebook.fresco:fresco:1.5.0' compile 'com.android.support:design:26.0.0-alpha1' compile 'com.android.support:support-v4:25.3.1'导入 xUtils.jar gson.jar
二, 主页面
1, activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="bw.com.bw1511a_month_test.MainActivity" android:orientation="vertical"> <android.support.design.widget.TabLayout android:layout_width="match_parent" android:layout_height="60dp" android:id="@+id/tab_layout_id"/> <android.support.v4.view.ViewPager android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/view_pager_id" /> </LinearLayout>
2, MainActivity.java
public class MainActivity extends AppCompatActivity { @BindView(R.id.tab_layout_id) TabLayout mTabLayout; private List<String> titles = new ArrayList<>();//标题 @BindView(R.id.view_pager_id) ViewPager mViewPager; private List<Fragment> data = new ArrayList<>();//数据源 private MyAdapter adapter; private Unbinder unbinder; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //绑定ButterKnife unbinder = ButterKnife.bind(this); //初始化标题 titles.add("NDK"); titles.add("WebView"); titles.add("动画"); titles.add("自定义View"); titles.add("aidl"); titles.add("获取数据"); //构建数据源 data.add(new NdkFragment()); data.add(new WebViewFragment()); data.add(new AnimationFragment()); data.add(new CustomFragment()); data.add(new AidlFragment()); data.add(new DataFragment()); adapter = new MyAdapter(getSupportFragmentManager()); mViewPager.setAdapter(adapter); //tabLayout 和 ViewPager 结合 mTabLayout.setupWithViewPager(mViewPager); } class MyAdapter extends FragmentPagerAdapter { public MyAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { return data.get(position); } @Override public int getCount() { return data.size(); } @Override public CharSequence getPageTitle(int position) { return titles.get(position); } } @Override protected void onDestroy() { super.onDestroy(); //解绑 unbinder.unbind(); } }
三, 第一个页面 --- NDK
环境配置路径: http://blog.****.net/xiuxiu_861223/article/details/78792939
页面: fragment_ndk.xml
<FrameLayout 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" tools:context="bw.com.bw1511a_month_test.pager1.NdkFragment"> <!-- TODO: Update blank fragment layout --> <TextView android:id="@+id/tv_id" android:layout_width="match_parent" android:layout_height="match_parent" android:textColor="@color/colorAccent" android:textSize="30sp"/> </FrameLayout>
1, 定义 .java 的文件
public class JniTest { //TODO 后面出现so包后加入即可 static{ System.loadLibrary("app"); } //------------------------------- //声明native 修饰的方法 public static native String getStr(); // javah -d jni -classpath ../../build/intermediates/classes/debug bw.com.bw1511a_month_test.pager1.JniTest }2, make module "app" -- 生成.class 文件
3, 在studio 的控制台中, 输入 javah的指令 -- 生成 .h 文件
javah -d jni -classpath ../../build/intermediates/classes/debug bw.com.bw1511a_month_test.pager1.JniTest(修改红色的部分为自己的包+类)
4, 在.h 所在的文件夹中, 创建一个和.h 同名的 .c 文件
5, 在.c 的文件中, 写入内容
bw_com_bw1511a_month_test_pager1_JniTest.c
//导包 #include "bw_com_bw1511a_month_test_pager1_JniTest.h" JNIEXPORT jstring JNICALL Java_bw_com_bw1511a_1month_1test_pager1_JniTest_getStr (JNIEnv *env, jclass jclass) { return (*env)->NewStringUTF(env,"Hello AS!!!!!!"); }
6, make module "app" --- so包
PS：如果构建出现下面错误：
在gradle.properties文件中追加下面代码即可：
android.useDeprecatedNdk=true
7, 回到 .java 文件中, 通过静态代码块, 引入so 包
static{
System.loadLibrary("app");
}
8, 在Fragment方法中, 可以通过调用.java 中的方法, 去调用.c的内容
7, 回到 .java 文件中, 通过静态代码块, 引入so 包
static{
System.loadLibrary("app");
}
8, 在Fragment方法中, 可以通过调用.java 中的方法, 去调用.c的内容

五, 第三个页面 -- 动画 -- 补间动画-- 实现 渐变, 缩放, 旋转, 位移, 集合的效果
1, fragment_animaction.xml
<LinearLayout 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:orientation="vertical" tools:context="bw.com.bw1511a_month_test.pager3.AnimationFragment"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <Button android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/but_01" android:text="渐变"/> <Button android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/but_02" android:text="缩放"/> <Button android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/but_03" android:text="旋转"/> <Button android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/but_04" android:text="位移"/> <Button android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/but_05" android:text="集合"/> </LinearLayout> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@mipmap/ic_launcher" android:layout_gravity="center" android:id="@+id/iv_id"/> </LinearLayout>

六, 第四个页面 -- 自定义View ---实现柱状图 + 扇形
1, 页面 fragment_custom.xml
<FrameLayout 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" tools:context="bw.com.bw1511a_month_test.pager4.CustomFragment"> <!-- TODO: Update blank fragment layout --> <bw.com.bw1511a_month_test.pager4.CustomView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/cs_id"/> </FrameLayout>
2, CustomView.java
/** * 柱状图 */ public class CustomView extends View{ private Paint paint;//画笔 private int rect_width = 30;//柱子的宽度 private int rect_space = 20;//柱子之间的间隔 private int[][] rects = {{Color.RED,300},{Color.GREEN,400},{Color.BLUE,500},{Color.YELLOW,600}}; public CustomView(Context context) { super(context); } public CustomView(Context context, @Nullable AttributeSet attrs) { super(context, attrs); paint = new Paint(); paint.setStrokeWidth(5);//设置画笔的粗细 paint.setAntiAlias(true);//设置抗锯齿 paint.setColor(Color.BLACK); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); //绘制300 canvas.drawText("300",10,getHeight()-350,paint); //绘制300 对应的 圆 canvas.drawCircle(50,getHeight()-350,5,paint); //绘制柱子 -- 循环 for(int i = 0;i<rects.length;i++) { paint.setColor(rects[i][0]);//设置画笔的颜色 int left = 50 +rect_space +(rect_space+rect_width)*i; int top = getHeight()-rects[i][1]-50; canvas.drawRect(left,top,left+rect_width,getHeight()-50,paint); } paint.setColor(Color.BLACK); //绘制X轴 canvas.drawLine(50,getHeight()-50,getWidth()-50,getHeight()-50,paint); canvas.drawLine(getWidth()-50,getHeight()-50,getWidth()-75,getHeight()-75,paint); canvas.drawLine(getWidth()-50,getHeight()-50,getWidth()-75,getHeight()-25,paint); //绘制Y轴 canvas.drawLine(50,50,50,getHeight()-50,paint); canvas.drawLine(50,50,25,75,paint); canvas.drawLine(50,50,75,75,paint); //绘制XY交汇处 canvas.drawCircle(50,getHeight()-50,5,paint); //绘制扇形 paint.setColor(Color.RED); RectF rectF = new RectF(500,500,900,900); canvas.drawArc(rectF,0,160,true,paint); } }
七, 第五个页面 -- AIDL -- 读取服务器中的数据库内容
需要 服务端 + 客户端
服务端:
1, 在src/main 目录中创建.aidl 文件
DataAidl.aidl
interface DataAidl { String getDbInfo(); }
2, 编译工程 -- 生成DataAidl.java文件
3, 数据库的创建 -- DbOpenHelper.java
/** * 数据库的帮助类 * */ public class DbOpenHelper extends SQLiteOpenHelper{ public DbOpenHelper(Context context) { super(context, "bw1511A.db", null, 1); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL("create table if not exists user(_id integer primary key autoincrement,uName,uPwd)"); db.execSQL("insert into user(uName,uPwd) values('abc','123')"); db.execSQL("insert into user(uName,uPwd) values('bcd','222')"); db.execSQL("insert into user(uName,uPwd) values('def','123')"); db.execSQL("insert into user(uName,uPwd) values('eee','234')"); db.execSQL("insert into user(uName,uPwd) values('tre','444')"); db.execSQL("insert into user(uName,uPwd) values('yui','123')"); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { } }
4, 创建服务 MyService.java
public class MyService extends Service { DataAidl.Stub stub = new DataAidl.Stub() { @Override public String getDbInfo() throws RemoteException { //获取数据库中的所有内容, 并且返回 DbOpenHelper dbOpenHelper = new DbOpenHelper(getApplicationContext()); SQLiteDatabase db = dbOpenHelper.getReadableDatabase(); Cursor cursor = db.rawQuery("select * from user",null); StringBuilder sBuilder = new StringBuilder(); while (cursor.moveToNext()) { String name = cursor.getString(cursor.getColumnIndex("uName")); String pwd = cursor.getString(cursor.getColumnIndex("uPwd")); sBuilder.append("姓名: " + name).append(", 密码: "+pwd).append("\n"); } Log.e("TAG","--" + sBuilder.toString()); return sBuilder.toString();
//不要忘记了Service 的注册啊
} }; @Nullable @Override public IBinder onBind(Intent intent) { return stub; }}5, 注册Service
<!--注册Service--> <service android:name=".MyService"> <intent-filter> <action android:name="com.bw.aidl"/> </intent-filter> </service>
客户端
1, 将服务器端的aidl 文件夹, 不做任何修改, 复制到 客户端的 src/mian 目录中
2, 编译工程 -- 生成DataAidl.java文件
3, AidlFragment.java
/** * 客户端 -- 服务器端 获取数据库中所有内容 *客户端: * 绑定服务 * 在绑定成功的回调方法中,得到 .ava 对象 * 可以根据对象, 调用方法 * */ public class AidlFragment extends Fragment { private Unbinder unbinder; @BindView(R.id.tv_id) TextView tv; //检测服务是否绑定成功 private ServiceConnection connection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { try { //获取aidl 对应的.java 文件 DataAidl dataAidl = DataAidl.Stub.asInterface(service); String str = dataAidl.getDbInfo(); tv.setText(str); } catch (RemoteException e) { e.printStackTrace(); } } @Override public void onServiceDisconnected(ComponentName name) { } }; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_aidl, container, false); //绑定 unbinder = ButterKnife.bind(this,view); return view; } //todo 绑定服务 @Override public void onResume() { super.onResume(); Intent intent = new Intent("com.bw.aidl"); intent.setPackage("bw.com.server");//5.0 后必须加--服务器的包名一致 getContext().bindService(intent,connection, Context.BIND_AUTO_CREATE); } //todo 解绑服务 @Override public void onPause() { super.onPause(); getContext().unbindService(connection); } @Override public void onDestroyView() { super.onDestroyView(); unbinder.unbind();//解绑 } }4, 页面 -- fragment_aidl.xml
<FrameLayout 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" tools:context="bw.com.bw1511a_month_test.pager5.AidlFragment"> <!-- TODO: Update blank fragment layout --> <TextView android:id="@+id/tv_id" android:layout_width="match_parent" android:layout_height="match_parent" android:text="@string/hello_blank_fragment" /> </FrameLayout>
八, 网络获取数据 -- xUtils获取数据, 展示到RecycleView 中, 图片获取用Fresco
1, 创建MyApp.java
public class MyApp extends Application { @Override public void onCreate() { super.onCreate(); //初始化 x.Ext.init(this); x.Ext.setDebug(true); Fresco.initialize(this); } }
2, 在清单文件中引入
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <application android:name=".MyApp" android:allowBackup="true"
