android中的Dialog的使用

   //一般弹窗     /*   DialogInterface.OnClickListener clickListener=new DialogInterface.OnClickListener()        {            @Override            public void onClick(DialogInterface dialog, int which) {            switch (which)            {                case Dialog.BUTTON_POSITIVE:                    Toast.makeText(MainActivity.this,"积极",Toast.LENGTH_SHORT).show();                    break;                case Dialog.BUTTON_NEGATIVE:                    Toast.makeText(MainActivity.this,"消极",Toast.LENGTH_SHORT).show();                    break;                case Dialog.BUTTON_NEUTRAL:                    Toast.makeText(MainActivity.this,"中立",Toast.LENGTH_SHORT).show();                    break;            }            }        };        AlertDialog.Builder dialog=new AlertDialog.Builder(this);        dialog.setTitle("提示");        dialog.setMessage("这是一个提示框！");        dialog.setPositiveButton("确定",clickListener);        dialog.setNegativeButton("取消",clickListener);        dialog.setNeutralButton("忽略",clickListener);        dialog.show();*/        //列表弹窗       /* AlertDialog.Builder builder=new AlertDialog.Builder(this);        final String[] strs={"哈哈","啦啦","呜呜"};        builder.setItems(strs, new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                Toast.makeText(MainActivity.this,strs[which],Toast.LENGTH_SHORT).show();            }        });        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                Toast.makeText(MainActivity.this,"确定",Toast.LENGTH_SHORT).show();            }        });        builder.create().show();*/        //加载弹窗        final ProgressDialog progress=new ProgressDialog(this);        progress.setMessage("加载中。。。");        progress.setCancelable(false);//屏蔽了返回键，一定要在数据加载完毕，dismiss否则会一直存在        progress.show();        final Handler handler=new Handler(){            @Override            public void handleMessage(Message msg) {                super.handleMessage(msg);                progress.dismiss();            }        };        new Thread(new Runnable() {            @Override            public void run() {                try {                    Thread.sleep(1000);                    handler.obtainMessage().sendToTarget();                } catch (InterruptedException e) {                    e.printStackTrace();                }            }        }).start();
内容比较简单，就不多说了，直接看看代码就可以啦。
