android 存储图片到data目录和读取data目录下的图片 _Android

历览千载书，时时见遗烈。这篇文章主要讲述android 存储图片到data目录和读取data目录下的图片相关的知识，希望能为你提供帮助。

public void storePic(String tabid, String key, Bitmap bitmap) {
LogUtils.LOGD(TAG, "storePic begin tabid = " + tabid + "key = " + key);
FileOutputStream fos = null;
try {
fos = getActivity().openFileOutput(tabid + "_" + key, Context.MODE_PRIVATE);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
} catch (FileNotFoundException e) {
LogUtils.LOGE(TAG, "storePic FileNotFoundException e = " +e);
} finally {
if(fos != null) {
try {
fos.flush();
fos.close();
} catch (IOException e) {
LogUtils.LOGE(TAG, "storePic IOException e = " +e);
}
}
}
}

public Bitmap getStorePic(String tabid, String key) {
LogUtils.LOGD(TAG, "getStorePic begin tabid = " + tabid + "key = " + key);
FileInputStream fin = null;
Bitmap bitmap = null;
try {
fin = getActivity().openFileInput(tabid + "_" + key);
bitmap = BitmapFactory.decodeStream(fin);
} catch (FileNotFoundException e) {
LogUtils.LOGE(TAG, "getStorePic FileNotFoundException e = " + e);
}
return bitmap;
}

总而流程：

存储图片代码：
[java] view plain copy
String str1 = "icon.png";

FileOutputStream localFileOutputStream1 = openFileOutput(str1, 0);

Bitmap.CompressFormat localCompressFormat = Bitmap.CompressFormat.PNG;

bitmap.compress(localCompressFormat, 100, localFileOutputStream1);

localFileOutputStream1.close();

【android 存储图片到data目录和读取data目录下的图片】读取图片代码：

[java] view plain copy
String localIconNormal = "icon.png";

FileInputStream localStream = openFileInput(localIconNormal);

Bitmap bitmap = BitmapFactory.decodeStream(localStream));
