分享現在有許多集成的,如友盟,ShareSDK等,或者直接去下載哪個App的分享SDK來集成,這些分享都是會提示來自xxx(appName)。如果不需要,可以簡單通過Intent.ACTION_SEND來實現分享功能
分享
下面通過一段代碼來看看分享的實現
public static void share(Context context, String extraText) {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, extraText);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(
Intent.createChooser(shareIntent, context.getString(R.string.action_share)));
}
可以看到,僅只需要傳送上下文和內容,一次分享動作就實現
分享純文本
如上面,調用ShareUtil.share(this, "test share");
就實現了分享文本分享圖片
public static void share(Context context, Uri uri) {
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.setType("image/*");
context.startActivity(
Intent.createChooser(shareIntent, context.getString(R.string.action_share)));
}
調用方式:
File file = BitmapUtil.Drawable2File(this, R.mipmap.ic_launcher, Environment.getExternalStorageDirectory() + "/test.png");
uri = BitmapUtil.File2Uri(file);
ShareUtil.share(this, uri);
注意:這裏有寫SD卡動作,需要添加讀寫權限,6.0添加運行時判斷
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
- 分享多張圖片
public static void share(Context context, ArrayList<Uri> uris) {
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);
shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
shareIntent.setType("image/*");
context.startActivity(
Intent.createChooser(shareIntent, context.getString(R.string.action_share)));
}
調用方式:ShareUtil.share(this, uris);
接收分享
從分享動作可以看出,只是發了一個Intent出來,所以其它App也是沒有硬性要求接收你的分享數據 – 不寫接口咯,但我們可以自己寫個接收分享數據接口出來,也是幾行代碼。
AndroidManifest.xml
添加intent-filter
<activity android:name=".ShareReceiveActivity">
<intent-filter>
<action android:name="android.intent.action.SEND"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="image/*"/>
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/plain"/>
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND_MULTIPLE"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="image/*"/>
</intent-filter>
</activity>
- 分享接口

}
}
void handleSendText(Intent intent) {
String sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
if (sharedText != null) {

type.setText("type:text");
text.setText(sharedText);
}
}
void handleSendImage(Intent intent) {
Uri imageUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);

}

type.setText("type:multiple");
if (imageUris.size() == 2) {
image.setImageURI(imageUris.get(0));

}
}
