在xml中設定onclick屬性值，內部寫入一個String資料，在class檔案中使用此String作為方法名，即可實現其跳轉

public class ToastActivity extends BaseActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_toast);
    }

    public void
 
 onClickDefaultToast(View v) {
        Toast.makeText(this, "預設位置", Toast.LENGTH_LONG).show();
    }

    public void onClickCenterToast(View v) {
        Toast toast = Toast.makeText(this, "居中顯示", Toast.LENGTH_LONG);
        toast.setGravity(Gravity.CENTER, 0, 0);
        toast.show();
    }

    public
 
 void onClickTopToast(View v) {
        Display display = getWindowManager().getDefaultDisplay();
        int height = display.getHeight();
        Toast toast = Toast.makeText(this, "上部", Toast.LENGTH_LONG);
        toast.setGravity(Gravity.TOP, 0, height / 6);
        toast.show();
    }
