android進度按鈕

⑴ android中如何實現在自定義的listview中點擊一個按鈕一個對應的進度條載入求高手解答

private class Adatpter extends BaseAdapter{
@Override
public int getCount() {
return 5;
}

@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = getLayoutInflater().inflate(R.layout.test_list_try_item, null);
Button btn = (Button) view.findViewById(R.id.test_list_try_item_button);
btn.setOnClickListener(new OnBtnClickListener((ProgressBar) view.findViewById(R.id.test_list_try_item_progressbar)));
return view;
}
}

private class OnBtnClickListener implements OnClickListener{
private int progress = 0;
private ProgressBar bar = null;

public OnBtnClickListener(ProgressBar bar){
this.bar = bar;
}

@Override
public void onClick(View v) {
if(null != bar)
bar.setProgress(progress);
progress = (progress + 10)%100;
}

}
不知道你要的是不是這樣的效果。隨便寫的，能用，希望能幫到你

⑵ android編程里如何使用按鈕來增加和減少進度條的進度

java">//這個是增加的，把這看懂，減的也就會了
packagecom.example.progressbardemo;

importandroid.app.Activity;
importandroid.os.Bundle;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.widget.Button;
importandroid.widget.ProgressBar;

{

	privateProgressBarone;
	privateButtonbutton;
	privateinti=0;
	@Override
	protectedvoidonCreate(BundlesavedInstanceState){
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		one=(ProgressBar)findViewById(R.id.progressBar2);
		button=(Button)findViewById(R.id.button1);
		button.setOnClickListener(newOnClickListener(){
			
			@Override
			publicvoidonClick(Viewarg0){
				if(i==0){
					one.setVisibility(View.VISIBLE);
				}
				elseif(i<one.getMax())
				{
					one.setProgress(i);
				}
				else
				{
					one.setVisibility(View.GONE);
					i=0;
				}
				i+=5;
			}
		});
	}

	

}
