首先需要在
AndroidManifest.xml
修改
<
activity
android
:name=
“com.test.apptest.AppActivity”
android
:label=
“@string/app_name”
android:launchMode=”singleTask”
>
//
Activity的Launch mode详解
<
intent-filter
>
<
action
android
:name=
“android.intent.action.MAIN”
/>
<
action
android
:name=
“android.intent.action.VIEW”
/>
<
category
android
:name=
“android.intent.category.LAUNCHER”
/>
</
intent-filter
>
<
intent-filter
>
<
action android:name=”android.intent.action.VIEW”
/>
<
data android:scheme=”apptest”/>
<
category android:name=”android.intent.category.DEFAULT”
/>
<
category android:name=”android.intent.category.BROWSABLE”
/>
</
intent-filter
>
</
activity
>
以
singleTask
或
singleInstance
方式
如果
Activity
已经启动过了会重新唤醒 （从app 跳转到网页或其它app 在跳转回来）
protected void
onNewIntent(Intent intent) {
super
.onNewIntent(intent);
setIntent(intent);
//here we can use getIntent() to get the extra data.
}
@Override
protected void
onResume() {
super
.onResume();
onNewIntent(
this
.getIntent());
Intent
intent = getIntent();
String scheme = intent.getScheme();
Uri uri = intent.getData();
System.
out
.println(
“scheme:”
+scheme);
if
(uri !=
null
) {
String host = uri.getHost();
String dataString = intent.getDataString();
String id = uri.getQueryParameter(
“d”
);
String path = uri.getPath();
String path1 = uri.getEncodedPath();
String queryString = uri.getQuery();
System.
out
.println(
“host:”
+host);
System.
out
.println(
“dataString:”
+dataString);
System.
out
.println(
“id:”
+id);
System.
out
.println(
“path:”
+path);
System.
out
.println(
“path1:”
+path1);
System.
out
.println(
“queryString:”
+queryString);
}
}
如果
Activity
没有启动过 则重新创建 （从网页或其它app 打开app）
protected void
onCreate(Bundle savedInstanceState) {
super
.onCreate(savedInstanceState);
Intent
intent = getIntent();
String scheme = intent.getScheme();
Uri uri = intent.getData();
System.
out
.println(
“scheme:”
+scheme);
if
(uri !=
null
) {
String host = uri.getHost();
String dataString = intent.getDataString();
String id = uri.getQueryParameter(
“d”
);
String path = uri.getPath();
String path1 = uri.getEncodedPath();
String queryString = uri.getQuery();
System.
out
.println(
“host:”
+host);
System.
out
.println(
“dataString:”
+dataString);
System.
out
.println(
“id:”
+id);
System.
out
.println(
“path:”
+path);
System.
out
.println(
“path1:”
+path1);
System.
out
.println(
“queryString:”
+queryString);
}
}
