Android中的常用的对话框

Android中常用的对话框总结：

确定取消对话框：

//确定取消对话框
	public void onclick01(View view){
		//工厂模式
		AlertDialog.Builder builder = new Builder(this);
		//设置对话框的参数
		builder.setTitle("警告");
		builder.setMessage("你确定删除这份文件吗？");
		//确认
		builder.setPositiveButton("确定", new OnClickListener() {
			@Override
			public void onClick(DialogInterface dialog, int which) {
				Toast.makeText(MainActivity.this, "已成功删除该文件", 0).show();
			}
		});
		//取消
		builder.setNegativeButton("取消", new OnClickListener() {
			@Override
			public void onClick(DialogInterface dialog, int which) {
				Toast.makeText(MainActivity.this, "该文件没有被删除", 0).show();
				
			}
		});
		AlertDialog dialog = builder.create();
		dialog.show();
	}

单选对话框：

//单选对话框
	public void onclick02(View view){
		AlertDialog.Builder builder = new Builder(this);
		//设置标题
		builder.setTitle("请选择你的性别?");
		final String[] items = {"男","女","妖"};
		builder.setSingleChoiceItems(items, 0, new OnClickListener() {
			@Override
			public void onClick(DialogInterface dialog, int which) {
				dialog.dismiss();
				Toast.makeText(MainActivity.this, items[which]+"被选中了", 0).show();
			}
		});
		builder.show();
	}

多选对话框：

//多选对话框
	public void onclick03(View view){
		AlertDialog.Builder builder = new Builder(this);
		builder.setTitle("请选择你的喜欢的水果？");
		final String[] items={"香蕉","苹果","荔枝","葡萄","西瓜"};
		final boolean[] checkedItems={false,true,true,false,false};
		builder.setMultiChoiceItems(items, checkedItems, new OnMultiChoiceClickListener() {
			@Override
			public void onClick(DialogInterface dialog, int which, boolean isChecked) {
				checkedItems[which]=isChecked;
			}
		});
		//提交
		builder.setPositiveButton("提交", new OnClickListener() {
			@Override
			public void onClick(DialogInterface dialog, int which) {
				StringBuffer sb = new StringBuffer();
				for (int i = 0; i < checkedItems.length; i++) {
					if(checkedItems[i]){
						sb.append(items[i]);
						sb.append(" ");
					}
				}
				Toast.makeText(MainActivity.this, "你选择了:"+sb.toString(), 0).show();
			}
		});
		builder.show();
	}

进度对话框：

//进度对话框
	public void onclick04(View view){
		final ProgressDialog dialog = new ProgressDialog(this);
		//设置标题
		dialog.setTitle("提醒");
		//设置内容
		dialog.setMessage("正在提交...");
		//要进行多久，一般写在另外一线程中。如果现在主线程中，会卡在这里，过一会才会显示进度对话框，这样很是不好
		new Thread(){
			public void run() {
				try {
					Thread.sleep(3000);
				} catch (InterruptedException e) {
					throw new RuntimeException(e);
				}
				dialog.dismiss();
			};
		}.start();
		dialog.show();
	}

进度条对话框：

//进度条对话框
	public void onclick05(View view){
		final ProgressDialog dialog = new ProgressDialog(this);
		//设置对话框进度的样式（水平方向）
		dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
		//设置进度的最大值
		dialog.setMax(100);
		//设置标题
		dialog.setTitle("提醒");
		//设置内容
		dialog.setMessage("正在保存...");
		new Thread(){
			public void run() {
				for (int i = 0; i < 100; i++) {
					try {
						Thread.sleep(500);
					} catch (InterruptedException e) {
						throw new RuntimeException(e);
					}
					dialog.setProgress(i);
				}
				dialog.dismiss();
			};
		}.start();
		dialog.show();
	}
