What I have tried:
my splash.java code:
package com.example.ne;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class splash extends Activity{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread timer = new Thread()
{
public void run(){
try{
sleep(6000);
} catch(InterruptedException e){
e.printStackTrace();
}finally{
Intent open =new Intent("com.example.ne.MAINACTIVITY");
startActivity(open);
}
}
};
timer.start();
}
}
和mainactivity.java代码：
and mainactivity.java code:
package com.example.ne;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends Activity {
int counter;
Button add,sub;
TextView display;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
counter=0;
add=(Button) findViewById(R.id.bAdd);
sub=(Button)findViewById(R.id.bSub);
display=(TextView)findViewById(R.id.tvdisplay);
add.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
counter++;
// TODO Auto-generated method stub
display.setText("Your total is" + counter);
}
});
sub.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
counter--;
display.setText("Your total is" + counter);
// TODO Auto-generated method stub
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
和manifest.xml代码：
< manifest xmlns：android =http://schemas.android.com/apk/res/android> ;
package =com.example.ne
android：versionCode =1
android：versionName =1.0>
< uses-sdk>
android：minSdkVersion =8

< application>
android：allowBackup =true
android： icon =@ drawable / ic_launcher

推荐答案
我和谢尔盖在这个问题上你需要自己解决这个问题，所以你明白了。 />
停止抨击代码并坐下来拿一张纸并写下该oncreate中发生的事情的顺序。
当你开始编写线程时，你需要查看你所要求的序列而不是代码。
I am with Sergey on this one and you need to fix this yourself, so you understand.
Stop just bashing code and sit and get a piece of paper and write the sequence of what happens in that oncreate.
When you start writing threads you need to sometimes look at the sequence you have asked for NOT THE CODE.
