Android 跳到一个新的Activity

  button.setOnClickListener(new OnClickListener(){
			@Override
			public void onClick(View v) {
				// Starting Another Activity
				Intent intent = new Intent(TestActivity.this , T2Activity.class);
			    //EditText editText = (EditText) findViewById(R.id.edit_message);
			    //String message = editText.getText().toString();
			    //intent.putExtra(EXTRA_MESSAGE, "abcc");
			    startActivity(intent);
			}        	 
         });
