在preSS按钮乍一听活跃。然后preSS该按钮再次将停止和第二声控我的code是OK？

              txt.setText（q）的;

          }
        }
      };
    }
 

解决方案

添加一行：

  mp.setLooping（真正的）;
 

然后，当你想停止循环设置为false。

When press button first sound active. Then press that button again it will stop and second sound active My code is OK?

                }catch(Exception ex){
                    ex.printStackTrace();
                }
                    }
                };
                t.start();

                }

        });

  }

      // our handler
      Handler handler = new Handler() {
        public void handleMessage(Message msg) {//display each item in a single line
          {

              Random rgenerator = new Random();
              Resources res = getResources();
              myString = res.getStringArray(R.array.myArray);
              String q = myString[rgenerator.nextInt(myString.length)];
              txt.setText(q);

          }
        }
      };
    }

Add the line:

mp.setLooping(true);

Then set false when you want to stop it looping.
