QQ分享官方第三方接入（分享纯图片及截取view的bitmap图）
常见功能Mark：QQ分享官方第三方接入。
一、创建并配置工程
参考腾讯官方文档： 点击打开链接简单抄过来一些：
1、创建一个工程，并把open-sdk.jar文件和mta_sdk_x.x.x.jar文件拷贝到libs（或lib）目录下
2. 配置AndroidManifest
在应用的AndroidManifest.xml增加配置的
二、正文配置QQ分享Demo：
一）实例化： private Tencent mTencent;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initViews();
// Tencent类是SDK的主要实现类，开发者可通过Tencent类访问腾讯开放的OpenAPI。
// 其中APP_ID是分配给第三方应用的appid，类型为String。
mTencent = Tencent.createInstance("222222",
this.getApplicationContext());
// 1.4版本:此处需新增参数，传入应用程序的全局context，可通过activity的getApplicationContext方法获取
bt_1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Bitmap b;
if (tv_1.getDrawingCache() != null) {
b = tv_1.getDrawingCache();
} else {
b = loadBitmapFromView(tv_1);
}
saveBitmap(b);
onClickShareToQQ();
Toast.makeText(getApplicationContext(), "保存成功",
Toast.LENGTH_SHORT).show();
}
});
}
private void onClickShareToQQ() {
Bundle shareParams = new Bundle();
shareParams.putInt(QQShare.SHARE_TO_QQ_KEY_TYPE,
QQShare.SHARE_TO_QQ_TYPE_IMAGE);
shareParams.putString(QQShare.SHARE_TO_QQ_IMAGE_LOCAL_URL,
File.getPath() + picName);
shareParams.putString(QQShare.SHARE_TO_QQ_APP_NAME, "LPS CRM");
shareParams.putInt(QQShare.SHARE_TO_QQ_EXT_INT,
QQShare.SHARE_TO_QQ_FLAG_QZONE_ITEM_HIDE);
doShareToQQ(shareParams);
}
private void doShareToQQ(Bundle params) {
mTencent.shareToQQ(MainActivity.this, params, new BaseUiListener() {
protected void doComplete(JSONObject values) {
Toast.makeText(getApplicationContext(), "成功",
Toast.LENGTH_SHORT);
}
@Override
public void onError(UiError e) {
}
@Override
public void onCancel() {
}
});
}private class BaseUiListener implements IUiListener {
@Override
public void onCancel() {
// TODO Auto-generated method stub
}
@Override
public void onComplete(Object arg0) {
// TODO Auto-generated method stub
}
@Override
public void onError(UiError arg0) {
// TODO Auto-generated method stub
}
}注释：
核心代码：抓取view图片缓存保存bitmap判空代码：
public static Bitmap loadBitmapFromView(View v) {
if (v == null) {
return null;
}
v.setDrawingCacheEnabled(true);
Bitmap screenshot;
v.measure(MeasureSpec.makeMeasureSpec(v.getWidth(),
MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(
v.getHeight(), MeasureSpec.UNSPECIFIED));
v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
v.buildDrawingCache();
screenshot = v.getDrawingCache();
if (screenshot == null) {
v.setDrawingCacheEnabled(true);
screenshot = Bitmap.createBitmap(v.getWidth(), v.getHeight(),
Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(screenshot);
c.translate(-v.getScrollX(), -v.getScrollY());
v.draw(c);
return screenshot;
}
return screenshot;
}
1）保存图片到本地
/**
* 保存图片到本地
* */
public void saveBitmap(Bitmap bm) {
isHaveSDCard();
if (isHaveSDCard()) {
File = Environment.getExternalStorageDirectory();
} else {
File = Environment.getDataDirectory();
}
File = new File(File.getPath() + "/MotieReader/data/");
if (!File.isDirectory()) {
File.delete();
File.mkdirs();
}
if (!File.exists()) {
File.mkdirs();
}
writeBitmap(File.getPath(), picName, bm);
}
/**
* 保存图片
*
* @param path
* @param name
* @param bitmap
*/
public static void writeBitmap(String path, String name, Bitmap bitmap) {
File file = new File(path);
if (!file.exists()) {
file.mkdirs();
}
File _file = new File(path + name);
if (_file.exists()) {
_file.delete();
}
FileOutputStream fos = null;
try {
fos = new FileOutputStream(_file);
if (name != null && !"".equals(name)) {
int index = name.lastIndexOf(".");
if (index != -1 && (index + 1) < name.length()) {
String extension = name.substring(index + 1).toLowerCase();
if ("png".equals(extension)) {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
} else if ("jpg".equals(extension)
|| "jpeg".equals(extension)) {
bitmap.compress(Bitmap.CompressFormat.JPEG, 75, fos);
}
}
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} finally {
if (fos != null) {
try {
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
public boolean isHaveSDCard() {
String SDState = android.os.Environment.getExternalStorageState();
if (SDState.equals(android.os.Environment.MEDIA_MOUNTED)) {
return true;
}
return false;
