Android如何实现本地图片直接分享到微信、来往、QQ等，

直接分享图片到指定应用-电脑资料

例如：要在app中直接分享图片到微信、来往等，而不调用他们

的sdk

直接贴代码如下;

public void shareImage(Bitmap bitmap) {

Uri uriToImage

null, bitmap,

try {

=

(Image(

tentResolver(),

null)); Intent shareIntent = new Intent();

ion(_SEND);

e("image/*");

ra(_STREAM, uriToImage);

// 遍历所有支持发送图片的应用，。找到需要的应用

PackageManager packageManager

=

kageManager();

ListresolveInfoList = packageManager

.queryIntentActivities(shareIntent,

_INTENT_FILTERS);

ComponentName componentName = null;

for (int i = 0; i < (); i++) {

if ((

(i).eName,

YouNeedAppPackageName)) {

componentName

= new

ComponentName(

(i).eName,

败");

(i).);

break;

}

// 已安装**

if

(null

}

}

!=

componentName) {

ponent(componentName);

ctivity(shareIntent);

}

}

} catch (Exception e) {

else {

tance().showToastMsg("请先安装**");

tance().showToastMsg("分享图片到**失

}

参考的文章如下：

android设置应用程序默认值

Android中有时打开一个文件,系统会弹出一个应用程序选择列表

供你选择.如果你把某个应用程序设为默认值,则不会弹出选择框,而会直

接调用该程序.

设置方法如下:

PackageManager pm = getPackageManager();

IntentFilterfilter = new IntentFilter();

egory("T");

ComponentName

ppClassName");

ComponentName[]

ComponentName[]{new

ComponentName("YourPreferAppPakageName","YourPreferApp

ClassName"), component};

ackagePreferredActivities("YourClearAppPakageN

ame");

ferredActivity(filter,_CATEGOR

components = new

component =

newComponentName("YourClearAppPakageName","YourClearA

Y_EMPTY, components, component);

列入修改系统默认Launhcer但不是唯一的Launcher

PackageManager pm = getPackageManager();

/>

IntentFilter filter = new IntentFilter();

ion("");

de>

egory("");

egory("

T");

Context context = getApplicationContext();

ComponentName

TestReplaceHomeAppActivi

component = new

ComponentName(kageName(),

/>e());

ComponentName[] components = new ComponentName[] {new

ComponentName("er",

"er"), component};

ackagePreferredAct

/>ivities("er"); ferredActivity(filter,

_CATEGORY_EMPTY,

component);

修改默认浏览器

PackageManager

=kageManager();

"T";

"BLE";

"";

//设置默认项的必须参数之一,用户的操作符合该过滤器时,默认设

String

String

String

packageManager

str1

str2

str3

=

=

=

components,

置起效 IntentFilter filter = new IntentFilter(str3);

egory(str1);

ComponentName

ComponentName(context

e());

component

egory(str2);

= new

aScheme("http"); //设置浏览页面用的Activity

.getPackageName(),

Intent intent = new Intent(str3); egory(str2);

egory(str1); Uri uri = ("");

aAndType(uri, null);

//找出手机当前安装的所有浏览器程序 List resolveInfoList =

packageManager

int

= 0;

size

i <

=

.queryIntentActivities(intent,

();

size; i++) {

ComponentName[]

activityInfo

=

置

=

}

_INTENT_FILTERS);

arrayOfComponentName = newComponentName[size]; for (int i

ActivityInfo

String

的默

=(i).activityInfo;

//

);

清除之前

packageName

认设

eName; String className = ;

ackagePreferredActivities(packageName

ComponentName

=

componentName

componentName;

newComponentName(packageName,

arrayOfComponentName[i]

ferredActivity(filter,

_CATEGORY_SCHEME,arrayOfComponentNa

me, component);

className);
