2、项目结构图

这上面项目结构图也是一目了然，有什么功能展示。大家也看到了，这上面类有点多，如果全部贴出来，不大可能，有兴趣下载本文源码。

3、看看基础类BaseActivity

我就贴一下基础类，还有实现类。因为这些一段段代码易于其他项目使用。

	}

	protected void putAsyncTask(AsyncTask<Void, Void, Boolean> asyncTask) {
		mAsyncTasks.add(asyncTask.execute());
	}

	protected void clearAsyncTask() {

	}

	/** 默认退出 **/
	protected void defaultFinish() {

	}
}

4、BasePopupWindow

package com.org.base;

import android.annotation.TargetApi;
import android.content.Context;
import android.graphics.drawable.BitmapDrawable;
import android.os.Build;
import android.util.AttributeSet;
import android.view.Gravity;
import android.view.View;
import android.widget.PopupWindow;

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public abstract class BasePopupWindow extends PopupWindow {

	protected View mContentView;
	protected onSubmitClickListener mOnSubmitClickListener;

	public BasePopupWindow() {
		super();
	}

	public BasePopupWindow(Context context, AttributeSet attrs,
			int defStyleAttr, int defStyleRes) {
		super(context, attrs, defStyleAttr, defStyleRes);
	}

	public BasePopupWindow(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
	}

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

	public BasePopupWindow(Context context) {
		super(context);
	}

	public BasePopupWindow(int width, int height) {
		super(width, height);
	}

	public BasePopupWindow(View contentView, int width, int height,
			boolean focusable) {
		super(contentView, width, height, focusable);
	}

	public BasePopupWindow(View contentView) {
		super(contentView);
	}

	@SuppressWarnings("deprecation")
	public BasePopupWindow(View contentView, int width, int height) {
		super(contentView, width, height, true);
		mContentView = contentView;
		setBackgroundDrawable(new BitmapDrawable());
		initViews();
		initEvents();
		init();
	}

	public abstract void initViews();

	public abstract void initEvents();

	public abstract void init();

	public View findViewById(int id) {
		return mContentView.findViewById(id);
	}

	/**
	 * 显示在parent的上部并水平居中
	 *
	 * @param parent
	 */
	public void showViewTopCenter(View parent) {
		showAtLocation(parent, Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0);
	}

	/**
	 * 显示在parent的中心
	 *
	 * @param parent
	 */
	public void showViewCenter(View parent) {
		showAtLocation(parent, Gravity.CENTER, 0, 0);
	}

	/**
	 * 添加确认单击监听
	 *
	 * @param l
	 */
	public void setOnSubmitClickListener(onSubmitClickListener l) {
		mOnSubmitClickListener = l;
	}

	public interface onSubmitClickListener {
		void onClick();
	}

}

5、BaseArrayListAdapter

package com.org.base;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;

//基本的适配器
public class BaseArrayListAdapter extends BaseAdapter {

	protected Context mContext;
	protected LayoutInflater mInflater;
	protected List<String> mDatas = new ArrayList<String>();

	//String数组添加数据源
	public BaseArrayListAdapter(Context context, String... datas) {
		mContext = context;
		mInflater = LayoutInflater.from(context);
		if (datas != null && datas.length > 0) {
			mDatas = Arrays.asList(datas);
		}
	}

	//用list方式添加数据源
	public BaseArrayListAdapter(Context context, List<String> datas) {
		mContext = context;
		mInflater = LayoutInflater.from(context);
		if (datas != null && datas.size() > 0) {
			mDatas = datas;
		}
	}

	@Override
	public int getCount() {
		return mDatas.size();
	}

	@Override
	public Object getItem(int position) {
		return mDatas.get(position);
	}

	@Override
	public long getItemId(int position) {
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		return null;
	}
}

6、实现自定义对话框，进度条以及popup弹出框，主MainActivity

package com.example.activity;

import com.org.base.BaseActivity;
import com.org.dialog.EditTextDialog;
import com.org.dialog.SimpleListDialog;
import com.org.dialog.SimpleListDialog.onSimpleListItemClickListener;
import com.org.popupwindow.ChatPopupWindow;
import com.org.popupwindow.ChatPopupWindow.onChatPopupItemClickListener;
import com.viw.adapt.CheckListDialogAdapter;

import android.R.layout;
import android.content.DialogInterface;
import android.os.Bundle;
import android.os.Handler;
import android.util.TypedValue;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.RelativeLayout;

public class MainActivity extends BaseActivity
implements
OnClickListener,
onChatPopupItemClickListener{

	protected SimpleListDialog mDialog;
	private int mCheckId = 0;
	private ChatPopupWindow mChatPopupWindow;
	private int mWidth;
	private int mHeaderHeight;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		findViewById(R.id.button1).setOnClickListener(this);
		findViewById(R.id.button2).setOnClickListener(this);
		findViewById(R.id.button3).setOnClickListener(this);
		findViewById(R.id.button4).setOnClickListener(this);
		findViewById(R.id.button5).setOnClickListener(this);
		initPopupWindow();
	}

	public void onSimpleListItem() {
		String[] modes = new String[]{"测试一","测试二","测试三"};
		mDialog = new SimpleListDialog(this);
		mDialog.setTitle("单选框");
		mDialog.setTitleLineVisibility(View.GONE);
		mDialog.setAdapter(new CheckListDialogAdapter(mCheckId, this, modes));
		//用匿名内部类实现接口监听
		mDialog.setOnSimpleListItemClickListener(new DialogItemClickListener());
		mDialog.show();
	}

	protected class DialogItemClickListener implements
			onSimpleListItemClickListener {

		@Override
		public void onItemClick(int position) {
			mCheckId = position;
		}
	}

	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.button1:

			showLoadingDialog("正在加载。。。");
			new Handler().postDelayed(new Runnable() {
				@Override
				public void run() {
					dismissLoadingDialog();

				}
			}, 10000);
			break;
		case R.id.button2:
			onSimpleListItem();
			break;
		case R.id.button3:
			onEditTextDialog();
			break;
		case R.id.button4:
			RelativeLayout layoutShow = (RelativeLayout)findViewById(R.id.layoutShow);
			mChatPopupWindow.showAtLocation(layoutShow, Gravity.RIGHT
					| Gravity.TOP, -10, mHeaderHeight + 10);
			break;
		case R.id.button5:
			startActivity(PullRefreshListViewActivity.class);
			break;
		default:
			break;
		}

	}

	private void onEditTextDialog() {
		final EditTextDialog mEditTextDialog = new EditTextDialog(this);
		mEditTextDialog.setTitle("填写推荐人");
		mEditTextDialog.setButton("取消",
				new DialogInterface.OnClickListener() {

					@Override
					public void onClick(DialogInterface dialog, int which) {
						mEditTextDialog.cancel();
					}
				}, "确认", new DialogInterface.OnClickListener() {

					@Override
					public void onClick(DialogInterface dialog, int which) {
						String text = mEditTextDialog.getText();
						if (text == null) {
							mEditTextDialog.requestFocus();
						} else {
							mEditTextDialog.dismiss();
						}
					}
				});
		mEditTextDialog.show();
	}

	//初始化PopupWindow
	protected void initPopupWindow() {
		mWidth = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
				130, getResources().getDisplayMetrics());
		mHeaderHeight = (int) TypedValue.applyDimension(
				TypedValue.COMPLEX_UNIT_DIP, 48, getResources()
						.getDisplayMetrics());
		mChatPopupWindow = new ChatPopupWindow(this, mWidth,
				LayoutParams.WRAP_CONTENT);
		mChatPopupWindow.setOnChatPopupItemClickListener(this);
	}

	//以下是popupwindow的选择监听事件
	@Override
	public void onVoiceModeClick() {
		showCustomToast("pop监听1");

	}

	@Override
	public void onCreateClick() {
		showCustomToast("pop监听2");
	}

	@Override
	public void onSynchronousClick() {
		showCustomToast("pop监听3");

	}

}

7、下拉刷新PullRefreshListViewActivity

package com.example.activity;

import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import com.org.base.BaseActivity;
import com.org.view.PullRefreshListView;
import com.org.view.PullRefreshListView.OnCancelListener;
import com.org.view.PullRefreshListView.OnRefreshListener;
import com.viw.adapt.CheckListDialogAdapter;

public class PullRefreshListViewActivity extends BaseActivity
implements
OnRefreshListener,
OnCancelListener,
OnItemClickListener{
	private PullRefreshListView mRefreshListView;
	String[] modes = new String[]{"测试一","测试二","测试三"};
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_refresh);

		initViews();
	}

	protected void initViews() {
		mRefreshListView = (PullRefreshListView) findViewById(R.id.otherfeedlist_mmrlv_list);
		//适配器我随便用了一个
		mRefreshListView.setAdapter(new CheckListDialogAdapter(1, this, modes));
		mRefreshListView.setOnItemClickListener(this);
		mRefreshListView.setOnRefreshListener(this);
		mRefreshListView.setOnCancelListener(this);
	}

	@Override
	public void onCancel() {
		//取消刷新
		mRefreshListView.onRefreshComplete();
	}

	@Override
	public void onRefresh() {

		//异步加载线程
		putAsyncTask(new AsyncTask<Void, Void, Boolean>() {
			@Override
			protected Boolean doInBackground(Void... params) {
				try {
					Thread.sleep(2000);
				} catch (InterruptedException e) {

				}
				return null;
			}

			@Override
			protected void onPostExecute(Boolean result) {
				super.onPostExecute(result);
				//这里写刷新adapt数据就行可以了

				mRefreshListView.onRefreshComplete();
			}
		});

	}

	@Override
	public void onItemClick(AdapterView<?> parent, View view, int position,
			long id) {
		// listview的单击事件就不写了

	}
}
