Android中的scheme

Scheme协议在Android中使用场景

• H5跳转到native页面
• 客户端获取push消息中后，点击消息跳转到APP内部页面
• APP根据URL跳转到另外一个APP指定页面

利用scheme协议跳转的一个完整实例

• 在Mainefest配置文件中配置需要用scheme协议跳转的Activity

<activity
    android:name=".SchemeActivity"
    android:label="@string/app_name">

    <!-- 要想在别的App上能成功调起App，必须添加intent过滤器 -->

    <!-- 协议部分，随便设置 -->
    <intent-filter>
        <!--协议部分，随便设置-->
        <data android:scheme="scheme" android:host="mtime" android:path="/goodsDetail" />
        <!--下面这几行也必须得设置-->
        <category android:name="android.intent.category.DEFAULT"/>
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.BROWSABLE"/>
    </intent-filter>
</activity>

• 模拟从网络中获取scheme协议的url

public class MainActivity extends AppCompatActivity {

    private TextView btnSchemeTv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btnSchemeTv = (TextView) findViewById(R.id.btn_scheme_tv);
        btnSchemeTv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                /**
                 * (1)在manifest配置文件中配置了scheme参数
                 * (2)网络端获取url
                 * (3)跳转
                 */
                String url = "scheme://mtime/goodsDetail?goodsId=10011002";

                Intent intent = new Intent(Intent.ACTION_VIEW,
                        Uri.parse(url));
                startActivity(intent);
            }
        });
    }
}

• 获取scheme协议参数

public class SchemeActivity extends Activity {
    private static final String TAG = "SchemeActivity";
    private TextView schemeTv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_scheme);
        schemeTv = (TextView) findViewById(R.id.scheme_tv);
        Uri data = getIntent().getData();
        Log.i(TAG, "host = " + data.getHost() + " path = " + data.getPath() + " query = " + data.getQuery());
        String param = data.getQueryParameter("goodsId");
        schemeTv.setText("获取的参数为：" + param);
    }
}
