Note: set your csv file name to match your database table name

any CSV file found in the data directory, will be read and the records will be inserted into the corresponding table whose name is similar to the file name. E.G. if you have a file called table_one.csv the records will be added into a database table called table_one. make sure that this table already exists in the database

look for code on how to create the CSV here ]]> https://assortmentofsites.com/android-sqllite-csv-to-database/feed/ 6 https://assortmentofsites.com/android-sqllite-table-to-csv/?utm_source=rss&utm_medium=rss&utm_campaign=android-sqllite-table-to-csv https://assortmentofsites.com/android-sqllite-table-to-csv/#comments Tue, 10 Jun 2014 18:14:57 +0000 admin http://assortmentofsites.com/?p=782 to convert any table to csv use the code below.

public boolean createCsvSaveToFile(Cursor cursor, String fileName) throws IOException {
String csv = "";
int colunmCount = cursor.getColumnCount(), i;
//check if extarnal drive is readerble
if (!isExternalStorageWritable()) {
fileError = "can not save to external storage";
fileinfo = "Please mount your SD card";
return false;
}
//create CSV
for (i = 0; i < colunmCount; i++) {//GET COLUNM NAMES
csv += QUOTES + cursor.getColumnName(i).toString() + QUOTES + INNER_DELIMITER;
}
csv = csv.replaceAll(",$", "");
csv += LINE_END;
if (cursor.moveToFirst()) {
do {
for (i = 0; i < colunmCount; i++) {//GET COLUNM values
csv += QUOTES + cursor.getString(i) + QUOTES + INNER_DELIMITER;
}
csv = csv.replaceAll(",$", "");
csv += LINE_END;
} while (cursor.moveToNext());
}
//save file
File file = getDataDir(fileName);
FileOutputStream out = new FileOutputStream(file);
out.write(csv.getBytes());
out.flush();
out.close();
return true;
}

 

private boolean isExternalStorageWritable() {
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
return true;
}
return false;
}

/* Create data dir or return it */
private File getDataDir(String tableCsv) throws IOException {
// Get the directory for the app data directory.
String f = tableCsv + ".csv";
File dataDirectory = new File(DATA_DIRECTORY, f);
if (!dataDirectory.exists()) {
if (!dataDirectory.createNewFile()) {
Log.e("getStorageDir", "file " + f + " not created");
fileError = "file " + f + " not created";
fileinfo = "unable to create backup file";
return null;
}
}
return dataDirectory;
}

just create a cursor with the appropriate data and call the function

you may set the file name to match the table name

look for code on how to add records into the android database from CSV here ]]> https://assortmentofsites.com/android-sqllite-table-to-csv/feed/ 0 https://assortmentofsites.com/android-radio-button-set-mulptiple-values/?utm_source=rss&utm_medium=rss&utm_campaign=android-radio-button-set-mulptiple-values https://assortmentofsites.com/android-radio-button-set-mulptiple-values/#comments Thu, 05 Jun 2014 13:20:22 +0000 admin http://assortmentofsites.com/?p=775 As i was working on an android app i released that i needed a radio button whose value was different from the display text. This is because the display text can be in any of several languages i.e Chinese, french, Japanese etc.

i extended the radio button class as below

import android.content.Context;
import android.util.AttributeSet;
import android.widget.RadioButton;

/**
*
* @author assortmentofsites
*/
public class multivalueRadioButton extends RadioButton{
String value;
String auxvalue;
public multivalueRadioButton(Context context) {
super(context);
}

public multivalueRadioButton(Context context, AttributeSet attrs) {
super(context, attrs);
}

public multivalueRadioButton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public void setValue(String v) { this.value = v; }
public String getValue() { return this.value; }
public void setAuxValue(String v) { this.auxvalue = v; }
public String getAuxValue() { return this.auxvalue; }
}

the custom radio button “multivalueRadioButto” can captuer two extra vales i.e value and  auxvalue

you can save the code in a file like “multivalueRadioButton.java”

Usage:

if you are getting data from a database and creating the custom radio buttons on the fly you can use a function like one below:

private RadioGroup inflateRg(RadioGroup rg, Cursor cursor) {

if (cursor.moveToFirst()) {
int i = 0;
do {
multivalueRadioButton rdbtn = new multivalueRadioButton(context);
rdbtn.setId(cursor.getInt(0)); //radio button id
rdbtn.setText(cursor.getString(1));//radio button name
rdbtn.setValue(cursor.getString(0));//extra value
rg.addView(rdbtn, i);
i++;
} while (cursor.moveToNext());
}
return rg;
}

simply get the data from the database into a cursor, call this function and you will have your radio group populated

i had installed pinterest for a client and after sometime the client noticed that on pining, pinterest was not picking the featured image.
i spent many hours going through the plugging code trying to find out the cause. When all had failed i noticed that the only images being picked from the page, were relatively large in size.
So i added a large size of the featured image into the post and to my surprise, it was picked by pinterest.
since this image was out of place, the only thing i had to do was to hide it.
the code below shows how i did it. you can add it to your theme files

global $post;
	$pcategory = get_the_category($post->ID);
	if($pcategory[0]->name == 'Recipe'){
		$meta = get_post_custom($post->ID);
		$photo_id = $meta['photo'][0];
		$photo = wp_get_attachment_image($photo_id, 'large', false, $attr);
		$photo = disect_page('src="', '" class=', $photo, array('en_offset'=>0));
		$photo = str_replace('src="', '', $photo);
	}

there are many ways to get the path to the featured image, the code above is just one of them

<img src="<?php echo $photo?>" style="opacity:0; position:absolute; top:0; left:0; filter:alpha(opacity=0);" />

add the above html at any place in your post template.  $photo contains the path to your image

the  style in the img tag, ensures that the image is not visible in any browser, even older versions of Internet explorer.

if you displayed featured image is small to the extent that pinterest does not pick it, use the code above to add a hidden larger version and pinterest will pick this.

On identifying the culprit please use all methods at your disposal to annihilate, obliterate and destroy this pain in the etc

or simply delete it

thank you
