自定义ListView

用FrameLayout自定义了一个ListView

代码如下：

public class EmptyListVisew extends FrameLayout {

    private ListView listView;
    private LinearLayout ll1;
    private LinearLayout ll2;

    public ListView getListView() {
        return listView;
    }

    public EmptyListVisew(Context context) {
        super(context);
        addListView();
    }

    public EmptyListVisew(Context context, AttributeSet attrs) {
        super(context, attrs);
        addListView();
    }

    public EmptyListVisew(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        addListView();
    }

    private void addListView() {

        listView = new ListView(getContext());
        LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT);
        listView.setLayoutParams(params);
        addView(listView);

    }

    public void setProgressView(String str) {

        setProgressView(null, str);

    }

    public void setProgressView(ProgressBar bar, String str) {

        ll1 = new LinearLayout(getContext());
        ll1.setOrientation(LinearLayout.VERTICAL);
        LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT);
        ll1.setGravity(Gravity.CENTER);
        ll1.setLayoutParams(params);
        if (bar == null) {
            bar = new ProgressBar(getContext());
        }

        TextView textView = new TextView(getContext());

        textView.setText(str);
        textView.setGravity(Gravity.CENTER);

        ll1.addView(bar);
        ll1.addView(textView);
        if (ll2 != null) {

            removeView(ll2);

        }
        addView(ll1);
        listView.setEmptyView(ll1);

    }

    public void setEmptyView(String str) {
        setEmptyView(-1, str,null);

    }

    public void setEmptyView(int rid, String str,OnClickListener click) {


        ll2 = new LinearLayout(getContext());
        ll2.setOrientation(LinearLayout.VERTICAL);
        LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT);
        ll2.setGravity(Gravity.CENTER);
        ll2.setLayoutParams(params);
        if (click!=null) {
            ll2.setOnClickListener(click);
        }

        if (rid != -1) {

            ImageView imageView = new ImageView(getContext());
            imageView.setImageResource(rid);
            ll2.addView(imageView);
        }
        TextView textView = new TextView(getContext());
        textView.setText(str);
        textView.setGravity(Gravity.CENTER);

        ll2.addView(textView);

        if (ll1 != null) {
            removeView(ll1);
        }

        addView(ll2);

        listView.setEmptyView(ll2);

    }

}

使用方法：

final EmptyListVisew elv = new EmptyListVisew(this);
        elv.setProgressView("正在加载中...");
        setContentView(elv);

        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                elv.setEmptyView(-1, "加载失败,点击刷新", new OnClickListener() {

                    @Override
                    public void onClick(View arg0) {

                        elv.setProgressView("继续加载...");
                    }
                });

            }
        }, 2000);

效果如下：
