我正在制作应用程序来听希腊语的 .mp3 单词并在 2000 毫秒后显示它们但是当我暂停线程然后 notify() 后线程永远不会再次运行... TextView 每 2000 毫秒更改一次但是当我暂停它并 notify() 运行时（ ) 块不再执行任何操作并且应用程序崩溃.. 我做错了什么？
class MyinnerThread implements Runnable {
String name;
Thread tr;
boolean suspendFlag;
int i = 0;
MyinnerThread(String threadname) {
name = threadname;
tr = new Thread(this, name);
suspendFlag = false;
tr.start();
}
public void run() {
try {
while(!suspendFlag){
runOnUiThread(new Runnable() {
@Override
public void run() {
if(i == 0){tv1.setText("trhead1");}
if(i == 1){tv2.setText("trhead2");}
if(i == 2){tv3.setText("trhead3");}
if(i == 3){tv4.setText("trhead4");}
if(i == 4){tv5.setText("trhead5");}
if(i == 5){tv6.setText("trhead6");}
if(i == 6){tv7.setText("trhead7");}
if(i == 7){tv8.setText("trhead8");}
synchronized(signal) {
while(suspendFlag) {
try {
signal.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
});
Thread.sleep(2000);
i++;
}
} catch (InterruptedException e) {
System.out.println(name + " interrupted.");
}
}
void mysuspend() {
suspendFlag = true;
}
void myresume() {
synchronized(signal) {
suspendFlag = false;
signal.notify();
}
}
}
编辑：这里的最终代码和工作！
run() {
try {
while(true){
synchronized(signal) {
while(suspendFlag) {
try {
signal.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
runOnUiThread(new Runnable() {
@Override
public void run() {
//....
}
}
});
Thread.sleep(2000);
i++;
}
}
}
}
