AndroidTwitter

AndroidTwitter is a small android library to let you connect to Twitter and access all it's public API (tweet status, retweet, etc).

How to Use

Here is a sample activity (TestConnect.java) to show how to connect to Twitter then save the access token. The access token then can be used later to access Twitter's public API (see TestPost.java)

public class TestConnect extends Activity {
	private TwitterApp mTwitter;
	private CheckBox mTwitterBtn;

	private static final String twitter_consumer_key = "xxx";
	private static final String twitter_secret_key = "xxxx";

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);

		mTwitterBtn	= (CheckBox) findViewById(R.id.twitterCheck);

		mTwitterBtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				onTwitterClick();
			}
		});

		mTwitter 	= new TwitterApp(this, twitter_consumer_key,twitter_secret_key);

		mTwitter.setListener(mTwLoginDialogListener);

		if (mTwitter.hasAccessToken()) {
			mTwitterBtn.setChecked(true);

			String username = mTwitter.getUsername();
			username		= (username.equals("")) ? "Unknown" : username;

			mTwitterBtn.setText("  Twitter (" + username + ")");
			mTwitterBtn.setTextColor(Color.WHITE);
		}

		Button goBtn = (Button) findViewById(R.id.button1);

		goBtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				startActivity(new Intent(TestConnect.this, TestPost.class));
			}
		});
	}

	private void onTwitterClick() {
		if (mTwitter.hasAccessToken()) {
			final AlertDialog.Builder builder = new AlertDialog.Builder(this);

			builder.setMessage("Delete current Twitter connection?")
			       .setCancelable(false)
			       .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
			           public void onClick(DialogInterface dialog, int id) {
			        	   mTwitter.resetAccessToken();

			        	   mTwitterBtn.setChecked(false);
			        	   mTwitterBtn.setText("  Twitter (Not connected)");
			        	   mTwitterBtn.setTextColor(Color.GRAY);
			           }
			       })
			       .setNegativeButton("No", new DialogInterface.OnClickListener() {
			           public void onClick(DialogInterface dialog, int id) {
			                dialog.cancel();

			                mTwitterBtn.setChecked(true);
			           }
			       });
			final AlertDialog alert = builder.create();

			alert.show();
		} else {
			mTwitterBtn.setChecked(false);

			mTwitter.authorize();
		}
	}

	private final TwDialogListener mTwLoginDialogListener = new TwDialogListener() {
		@Override
		public void onComplete(String value) {
			String username = mTwitter.getUsername();
			username		= (username.equals("")) ? "No Name" : username;

			mTwitterBtn.setText("  Twitter  (" + username + ")");
			mTwitterBtn.setChecked(true);
			mTwitterBtn.setTextColor(Color.WHITE);

			Toast.makeText(TestConnect.this, "Connected to Twitter as " + username, Toast.LENGTH_LONG).show();
		}

		@Override
		public void onError(String value) {
			mTwitterBtn.setChecked(false);

			Toast.makeText(TestConnect.this, "Twitter connection failed", Toast.LENGTH_LONG).show();
		}
	};
}
