android:android Intent and IntentFilter

android:android Intent and IntentFilter

 

1,intentfilter說明:

如果說是將一個activity有其他應用開啟,或者是在webView 或者 bybird app中調用我們自己的activity,
那麼就可以使用intentfilter來過濾我們自己需要的activity;

*uri參數說明 Java Code:

final Uri uri =  Uri.parse(intbird://com.intbird.soft/testing/tested?name='Test');        TextView textView = (TextView)findViewById(R.id.textView);        textView.setText(uri.getScheme() +  //intbird                        + uri.getPort() +   //-1                        + uri.getAuthority() +  //com.intbird.soft                        + uri.getHost() +   //com.intbird.soft                        + uri.getPath() +  // /testing/tested                        + uri.getPathSegments() +  // [tesing,tested]                        + uri.getQuery()+); // name='Text'

public void onClick(View v) {                Intent intent = new Intent();                intent.setAction(android.intent.action.VIEW);                intent.setData(uri);                PackageManager packageManager = getPackageManager();                List activities = packageManager.queryIntentActivities(intent,0);                boolean isIntentSafe  = activities.size() > 0;                if(isIntentSafe){                    startActivity(intent);                }else{                    Toast.makeText(MainActivity.this, 匹配None, Toast.LENGTH_SHORT).show();                }            }

XML Code:

NOTE : 必須有category標籤

2,結合網頁調用加深理解

uri:
final Uri urihttp = Uri.parse(“https://www.baidu.com/s?wd=intbird“);
//schma : http
//host : www.baidu.com
//path : /s
//query : wd= intbird

XML

匹配scheme,匹配host多個,彈出 Intent Chooser

3,同理,我們如果有多個activity;

if 兩個都一樣:

So:

but: add path [ android:path=”/testing” ] to one,startActivity directly
