用過的Intent的用法

原文地址 http://blog.csdn.net/qq_25806863/article/details/70145785

突然看到之前的一篇筆記，就補充一下發上來。Intent是什麼就先不說了。列表可以看一下目錄。

所有用法均在小米max手機上親測，android6.0。有些權限在6.0上要動態獲取。

以後如果用到新功能了再補充，沒用過的先不寫了。

打電話

使用ACTION_CALL需要android.permission.CALL_PHONE權限

    Intent intent=new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    //intent.setAction(Intent.ACTION_CALL);
    //intent.setAction(Intent.ACTION_DIAL);
    intent.setData(Uri.parse("tel:[phone]"));
    startActivity(intent);

發短信

• 1

    Intent intent= new Intent();
    intent.setData(Uri.parse("smsto:10086"));
    intent.setAction(Intent.ACTION_SENDTO);
    intent.putExtra("sms_body", "填信息內容");
    startActivity(intent);

• 2

Intent intent= new Intent();
                intent.setAction(Intent.ACTION_VIEW);
                intent.setType("vnd.android-dir/mms-sms");
                intent.putExtra("sms_body", "填信息內容");
                startActivity(intent);

發郵件

• 彈出選擇器

Intent intent=new Intent();
                intent.setAction(Intent.ACTION_SEND);
                //收件人
                String[] tos={"[email protected]"};
                //抄送人
                String[] ccs={"[email protected]"};
                intent.putExtra(Intent.EXTRA_EMAIL, tos);
                intent.putExtra(Intent.EXTRA_CC, ccs);
                intent.putExtra(Intent.EXTRA_TEXT, "郵件內容 2333");
                intent.putExtra(Intent.EXTRA_SUBJECT, "郵件主題");
                intent.setType("message/rfc822");
                startActivity(Intent.createChooser(intent, "選擇客戶端發送"));

• 直接啓動郵件客戶端

Intent intent=new Intent();
                intent.setData(Uri.parse("mailto:"));
                intent.setAction(Intent.ACTION_SENDTO);
                //收件人
                String[] tos={"[email protected]"};
                //抄送人
                String[] ccs={"[email protected]"};
                intent.putExtra(Intent.EXTRA_EMAIL, tos);
                intent.putExtra(Intent.EXTRA_CC, ccs);
                intent.putExtra(Intent.EXTRA_TEXT, "郵件內容 2333");
                intent.putExtra(Intent.EXTRA_SUBJECT, "郵件主題");
                //intent.setType("message/rfc822");
                startActivity(intent);

啓動相機

• 單純啓動相機

Intent intent = new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA);
startActivity(intent);

• 以錄像模式啓動相機

Intent intent = new Intent(MediaStore.INTENT_ACTION_VIDEO_CAMERA);
startActivity(intent);

• 獲取拍照返回的縮略圖 需要android.permission.CAMERA權限

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent,0);

然後在

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Bitmap bitmap = data.getParcelableExtra("data");
    }

回到桌面，HOME

Intent intent = new Intent();
                intent.setAction("android.intent.action.MAIN");
                intent.addCategory("android.intent.category.HOME");
                startActivity(intent);

從聯繫人選擇電話號碼

Intent intent = new Intent(Intent.ACTION_PICK);
                intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
                startActivityForResult(intent,0);

然後再

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Uri uri = data.getData();
        String[] names = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER};
        Cursor cursor = getContentResolver().query(uri, names,null, null, null);
        int index = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
        String number = cursor.getString(index);
        Log.i(TAG, "onActivityResult: "+number);
    }

插入新的聯繫人,跳到新建聯繫人頁面並自動填好信息。

                Intent intent = new Intent(Intent.ACTION_INSERT);
                intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
                intent.putExtra(ContactsContract.Intents.Insert.NAME, "aaa");
                intent.putExtra(ContactsContract.Intents.Insert.EMAIL, "wandjnfdjkn");
                intent.putExtra(ContactsContract.Intents.Insert.PHONE, "100200100");
                startActivity(intent);

安裝apk文件

    String fileName = Environment.getExternalStorageDirectory() + "/a.apk" ;
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.fromFile(new File(fileName)), "application/vnd.android.package-archive");
    startActivity(intent);

啓動QQ，並打開指定的聊天窗口

String url = "mqqwpa://im/chat?chat_type=wpa&uin=1492571688";
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));

打開手機上的地圖軟件，如百度地圖。傳入的座標如果在範圍內會直接點位到所傳的座標

Uri uri = Uri.parse("geo:40.2268400000,88.1141060000");
                Intent intent = new Intent(Intent.ACTION_VIEW,uri);
                startActivity(intent);

打開系統各各個設置頁面

如WiFi

Intent intent = new Intent(Settings.ACTION_WIFI_SETTINGS);
startActivity(intent);

其他如

ACTION_SETTINGS
ACTION_WIRELESS_SETTINGS
ACTION_AIRPLANE_MODE_SETTINGS
ACTION_WIFI_SETTINGS
ACTION_APN_SETTINGS
ACTION_BLUETOOTH_SETTINGS
ACTION_DATE_SETTINGS
ACTION_LOCALE_SETTINGS
ACTION_INPUT_METHOD_SETTINGS
ACTION_DISPLAY_SETTINGS
ACTION_SECURITY_SETTINGS
ACTION_LOCATION_SOURCE_SETTINGS
ACTION_INTERNAL_STORAGE_SETTINGS

用瀏覽器打開網頁

    Uri webpage = Uri.parse("http://www.baidu.com");
    Intent intent = new Intent(Intent.ACTION_VIEW, webpage);
    startActivity(intent);

打開錄音機
