Categories:

android, Learning

Now I want to show you how to show to the screen the SMS from your inbox/outbox. In this tutorial, you should permission to read sms first on your android manifest.

 <uses-permission android:name="android.permission.READ_SMS" />

1	<uses-permission android:name="android.permission.READ_SMS" />

This is the code, we use cursor to get the text.

public void readSMS() {
		String info = "";
		Uri mSmsinboxQueryUri = Uri.parse("content://sms");
		Cursor cursor1 = getContentResolver().query(
				mSmsinboxQueryUri,
				new String[] { "_id", "thread_id", "address", "person", "date",
						"body", "type" }, null, null, null);
		startManagingCursor(cursor1);
		String[] columns = new String[] { "address", "person", "date", "body",
				"type" };
		if (cursor1.getCount() > 0) {
			String count = Integer.toString(cursor1.getCount());
			Log.e("Count", count);
			while (cursor1.moveToNext()) {
				String address = cursor1.getString(cursor1
						.getColumnIndex(columns[0]));
				String name = cursor1.getString(cursor1
						.getColumnIndex(columns[1]));
				String date = cursor1.getString(cursor1
						.getColumnIndex(columns[2]));
				String msg = cursor1.getString(cursor1
						.getColumnIndex(columns[3]));
				String type = cursor1.getString(cursor1
						.getColumnIndex(columns[4]));
				info += address + "n" + name + "n" + date + "n" + msg + "n"
						+ type;
				txtInfo.setText(info);
			}
		}
	}

public void readSMS() {

String info = "";

Uri mSmsinboxQueryUri = Uri.parse("content://sms");

Cursor cursor1 = getContentResolver().query(

mSmsinboxQueryUri,

new String[] { "_id", "thread_id", "address", "person", "date",

"body", "type" }, null, null, null);

startManagingCursor(cursor1);

String[] columns = new String[] { "address", "person", "date", "body",

"type" };

if (cursor1.getCount() > 0) {

String count = Integer.toString(cursor1.getCount());

Log.e("Count", count);

while (cursor1.moveToNext()) {

String address = cursor1.getString(cursor1

.getColumnIndex(columns[0]));

String name = cursor1.getString(cursor1

.getColumnIndex(columns[1]));

String date = cursor1.getString(cursor1

.getColumnIndex(columns[2]));

String msg = cursor1.getString(cursor1

.getColumnIndex(columns[3]));

String type = cursor1.getString(cursor1

.getColumnIndex(columns[4]));

info += address + "n" + name + "n" + date + "n" + msg + "n"

+ type;

txtInfo.setText(info);

How to use getInstance() ?

Categories:

getInstance is usually used to help to make just one object and without parse it. for example, we parse parameter Object like this:

public class GpsData {
VarData vardata;
public GpsData(VarData data){
this.data = vardata;
}
}

public class GpsData {

public GpsData(VarData data){

this.data = vardata;

}

how to read a ‘strange class’

Categories:

I just wonder how people know how to use the strange class. let’s make an example. This is the class I got from developer.android, I used Telephony Manager, but you know,,, the calling method is different.

Class Overview
Provides access to information about the telephony services on the device. Applications can use the methods in this class to determine telephony services and states, as well as to access some types of subscriber information. Applications can also register a listener to receive notification of telephony state changes.
You do not instantiate this class directly; instead, you retrieve a reference to an instance through Context.getSystemService(Context.TELEPHONY_SERVICE).
Note that access to some telephony information is permission-protected. Your application cannot access the protected information unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the the methods through which you access the protected information.

and from the forum, the way to call the class is:

TelephonyManager telephon = (TelephonyManager)	context.getSystemService(Context.TELEPHONY_SERVICE);

1	TelephonyManager telephon = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
