[英]cannot convert from Runnable to Thread
I get this error message "cannot convert from Runnable to Thread" This comes up for the Threat T = new Runnable(r); 我收到此错误消息“无法从Runnable转换为线程”这出现了Threat T = new Runnable(r);
Here is my code... 这是我的代码......
final String[] texts = new String[]{player, player11, player111}; //etc
final Runnable r = new Runnable(){
public void run(){
for(final int i=0;i<texts.length;i++){
synchronized(this){
wait(30000); //wait 30 seconds before changing text
}
//to change the textView you must run code on UI Thread so:
runOnUiThread(new Runnable(){
public void run(){
TextView t = (TextView) findViewById(R.id.textView1);
t.setText(texts[i]);
}
});
}
}
};
Thread T = new Runnable(r);
T.start();
You have a wrong line in your code 您的代码中有一行错误的行
Change 更改
Thread T = new Runnable(r);
to 至
Thread T = new Thread(r);
Thread
实现了Runnable
,而不是相反。
Sherif's right. 谢里夫是对的。 I'd also recommend some code cleanup, to avoid all the runnables and threads you've got going.
我还建议一些代码清理,以避免你已经运行的所有runnables和线程。 Just use a handler to do your update, and request another update 30 seconds after the current update.
只需使用处理程序进行更新,并在当前更新后30秒请求另一次更新。 This will be handled on the UI thread.
这将在UI线程上处理。
TextView t;
Handler handler;
int count = 0;
@Override
public void onCreate(Bundle bundle)
{
t = (TextView) findViewById(R.id.textView1);
Handler handler = new Handler();
handler.post(uiUpdater);
}
Runnable uiUpdater = new Runnable()
{
@Override
public void run()
{
count = (count + 1) % texts.length;
t.setText(texts[count]);
handler.removeCallbacks(uiUpdater);
handler.postDelayed(uiUpdater, 30000);
}
};
