switch (v.getId()) { case R.id.btn1://确定取消对话框 //1获取一个对话框的创建器 AlertDialog.Builder builder=new Builder(MainActivity.this); //2所有builder设置一些参数 builder.setTitle("对话框标题"); builder.setMessage("提示是否退出"); builder.setPositiveButton("确定", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "确定按钮被点击",1).show(); } }); builder.setNeutralButton("取消",new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "取消按钮被点击",1).show(); } }); builder.create().show(); break; case R.id.btn2://pick对话框 AlertDialog.Builder builder2=new Builder(MainActivity.this); builder2.setTitle("选择一个人"); final String[] arr=new String[]{"张三","李四","王五"}; builder2.setItems(arr, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, arr[which], 1).show(); } }); builder2.create().show(); break; case R.id.btn3://带选择的单选按钮的对话框 AlertDialog.Builder builder3=new Builder(MainActivity.this); builder3.setTitle("选择一个颜色"); final String[] items=new String[]{"蓝色","黄色","红色"}; builder3.setSingleChoiceItems(items, 1, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, items[which], 1).show(); } }); builder3.create().show(); dialog3.dismiss(); break; case R.id.btn4://带选择的多选按钮的对话框 AlertDialog.Builder builder4=new Builder(MainActivity.this); builder4.setTitle("选择若干个颜色"); final String[] items4=new String[]{"蓝色","黄色","红色"}; builder4.setMultiChoiceItems(items4, new boolean[]{false,false,false}, new DialogInterface.OnMultiChoiceClickListener() { public void onClick(DialogInterface dialog, int which, boolean isChecked) { Toast.makeText(MainActivity.this, items4[which]+"选择状态"+isChecked, 1).show(); } }); builder4.setPositiveButton("确定",new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }); dialog3=builder4.create(); dialog3.show(); break; case R.id.btn5://进度条的对话框 ProgressDialog pd=new ProgressDialog(this); pd.setTitle("提示"); pd.setMessage("正在加载中，请稍后..."); pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);//设置带进度条的 pd.setMax(100); pd.show(); pd.setProgress(50); break; }
