        android:layout_height="wrap_content"
        android:background="#999999"
        android:orientation="horizontal" >

        <ImageView

            android:text="这是个小机器人"
            android:textColor="#ffffff"
            android:textSize="15dip" >
        </TextView>
    </LinearLayout>

</LinearLayout>

public class MainActivity extends Activity implements OnClickListener {
	private Button btn1;
	private Button btn2;
	private Button btn3;
	private Button btn4;
	private Button btn5;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		btn1 = (Button) findViewById(R.id.sys_btn);
		btn2 = (Button) findViewById(R.id.define_location_btn);
		btn3 = (Button) findViewById(R.id.define_img_btn);
		btn4 = (Button) findViewById(R.id.define_btn);
		btn5 = (Button) findViewById(R.id.long_btn);
		
		btn1.setOnClickListener(this);
		btn2.setOnClickListener(this);
		btn3.setOnClickListener(this);
		btn4.setOnClickListener(this);
		btn5.setOnClickListener(this);
		
	}

	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.sys_btn:
			Toast.makeText(MainActivity.this, "这是系统默认的吐丝", 0).show();
			break;
		case R.id.define_location_btn:
			Toast t = Toast.makeText(MainActivity.this, "这是自定义位置的吐丝", 0);
			t.setGravity(Gravity.CENTER, 0, 0);
			t.show();
			break;
		case R.id.define_img_btn:
			Toast t2 = Toast.makeText(MainActivity.this, "这是带图片的的吐丝", 0);
			t2.setGravity(Gravity.CENTER, 0, 0);
			LinearLayout ll = (LinearLayout) t2.getView();
			ImageView img = new ImageView(MainActivity.this);
			img.setImageResource(R.drawable.ic_launcher);
			ll.addView(img, 0);
			t2.show();

			break;
		case R.id.define_btn:
			View view = getLayoutInflater().inflate(R.layout.userdefinedtoast,
					(GridView) findViewById(R.id.toast_layout));

			Toast t4 = new Toast(getApplicationContext());
			t4.setDuration(0);
			t4.setView(view);
			t4.show();
			break;
		case R.id.long_btn:
			View view5 = getLayoutInflater().inflate(R.layout.userdefinedtoast,
					(GridView) findViewById(R.id.toast_layout));
			Builder b = new AlertDialog.Builder(MainActivity.this);
			b.setView(view5);
			b.create();
			b.show();
