我在 ICS 4.0.3 上运行线程时遇到问题
我制作了该 apk,并将其安装在 2.33 SE 手机和 Google Nexus S 4.0.3 上。
在 SE 上,apk 正在按预期运行和加载。然而,在 Nexus 上我收到一个错误,我必须关闭它。但我看到程序在后面运行。 我尝试从代码中删除线程(加载屏幕、启动图片)并在 Nexus 上再次运行它,它可以运行。所以我发现我的问题出在线程上,onCreate 线程启动。 2.33 到 4.0.3 有什么区别吗?
package my.LigTv.Browser;
import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.MotionEvent;
import android.webkit.WebView;
import android.app.AlertDialog;
public class LigTVBrowserActivity extends Activity {
/** Called when the activity is first created. */
WebView mWebView;
AlertDialog alertDialog;
protected boolean _active = true;
protected int _splashTime = 3000; // time to display the splash screen in ms
int progress = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
final Activity activity = this;
final ProgressDialog progressDialog = new ProgressDialog(activity);
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressDialog.setMessage("Please wait for the applet to load");
progressDialog.show();
progressDialog.setProgress(0);
activity.setProgress(progress * 1000);
progressDialog.incrementProgressBy(progress);
if(progress == 100 && progressDialog.isShowing())
progressDialog.dismiss();
Thread splashTread = new Thread() {
@Override
public void run() {
try {
int waited = 0;
while(_active && (waited < _splashTime)) {
sleep(100);
if(_active) {
waited += 100;
}
}
} catch(InterruptedException e) {
// do nothing
} finally {
finish();
startActivity(new Intent("my.LigTv.Browser.Starter"));
stop();
}
}
};
splashTread.start();
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
_active = false;
}
return true;
}
}
最佳答案
尝试在启动新 Activity 后调用finish()
。另外,为什么要在线程上调用 stop()
?一旦开始新的 Activity ,它将停止。这是我已经写好的示例,您可以随意更改:
Runnable r1 = new Runnable(){
public void run(){
new Handler().postDelayed(new Runnable(){
@Override
public void run(){
startActivity(new Intent(Splash.this,Main.class));
overridePendingTransition(R.anim.fade_out, R.anim.fade_in);
finish();
}
}, waitTime);
}
};
runOnUiThread(r1);
