我想将效果应用于搜索栏,如下所示:
我尝试过的如下。完整的代码在下面试试,如果你会得到下面的效果,请告诉我。
MainActivity.java
public class MainActivity extends Activity
{
private static int myProgress=0;
private SeekBar seekBar;
private int progressStatus=0;
private Handler myHandler=new Handler();
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.h_processbar);
}
public void beginYourTask(View view)
{
myProgress=0;
seekBar= (SeekBar)findViewById(R.id.seekBar);
seekBar.setMax(100);
new Thread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
while(progressStatus<100)
{
progressStatus=performTask();
myHandler.post(new Runnable()
{
public void run() {
seekBar.setProgress(progressStatus);
}
});
}
myHandler.post(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(),"Task Completed",Toast.LENGTH_LONG).show();
progressStatus=0;
myProgress=0;
}
});
}
private int performTask()
{
try {
//---Do some task---
Thread.sleep(100);
} catch (InterruptedException e)
{
e.printStackTrace();
}
return ++myProgress;
}
}).start();
}
}

任何帮助将不胜感激。
谢谢你。
