安卓常用弹出窗

1.提示
先来说一下“提示”（提示几秒后就会消失），也许你只是想提示一下，不需要对方反馈，甚至不需要对方一定看见，也许你需要的是这个：

Toast.makeText(QueryCarInfoActivity.this, "上传数据成功", Toast.LENGTH_SHORT).show();
//从资源文件string.xml 里面取提示信息
Toast.makeText(QueryCarInfoActivity.this, getString(R.string.hello), Toast.LENGTH_SHORT).show();

Toast.makeText(QueryCarInfoActivity.this, "上传数据成功", Toast.LENGTH_SHORT).show(); 
//从资源文件string.xml 里面取提示信息
Toast.makeText(QueryCarInfoActivity.this, getString(R.string.hello), Toast.LENGTH_SHORT).show();

参数：
Toast.LENGTH_SHORT: Show the view or text notification for a short period of time
Toast.LENGTH_LONG: Show the view or text notification for a long period of time

2.使用new AlertDialog.Builder(context)创建一个对话框
(1)确定框
点击时，弹出一个消息框

/**
* 确定框
*/
private void dialogShowOK() {
    new AlertDialog.Builder(this)
    .setTitle("确定框")
    .setMessage("简单消息框")
    .setPositiveButton("确定", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            //按钮事件
        }
    })
    .show();
}

	/**
	 * 确定框
	 */
	private void dialogShowOK() {
		new AlertDialog.Builder(this)
		.setTitle("确定框")
		.setMessage("简单消息框")
		.setPositiveButton("确定", new DialogInterface.OnClickListener() {
			
			public void onClick(DialogInterface dialog, int which) {
				//按钮事件
			}
		})
		.show();
	}

(2)确定取消框
确定还是取消，it is a problem，当你做某项操作时，弹出一个提示，来确保操作无误。如删除文件时，提示“确认删除文件”；当按返回按钮时，提示“确认退出”等。

    /**
     * 确定取消框
     */
    private void dialogShowOKCancel() {
        new AlertDialog.Builder(this)
        .setTitle("确定取消框")
        .setIcon(R.drawable.down)
        .setMessage("确定退出吗")
        .setPositiveButton("确定", new DialogInterface.OnClickListener() {

            public  void onClick(DialogInterface dialog, int which) {
                //确定按钮事件
                setResult(RESULT_OK);
//              dialog.dismiss();
                finish();
            }
        })
        .setNegativeButton("取消",  new DialogInterface.OnClickListener() {

            public void onClick(DialogInterface dialog, int which) {
                //取消按钮事件
//              dialog.dismiss();
            }
        })
        .show();
    }

    /**
     * 按返回键提示是否退出
     */
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
               dialogShowOKCancel();
        }
        return false;
    }

	/**
	 * 确定取消框
	 */
	private void dialogShowOKCancel() {
		new AlertDialog.Builder(this)
		.setTitle("确定取消框")
		.setIcon(R.drawable.down)
		.setMessage("确定退出吗")
		.setPositiveButton("确定", new DialogInterface.OnClickListener() {
			
			public void onClick(DialogInterface dialog, int which) {
				//确定按钮事件
				setResult(RESULT_OK);
//				dialog.dismiss();
				finish();
			}
		})
		.setNegativeButton("取消", new DialogInterface.OnClickListener() {
			
			public void onClick(DialogInterface dialog, int which) {
				//取消按钮事件
//				dialog.dismiss();
			}
		})
		.show();
	}

	/**
	 * 按返回键提示是否退出
	 */
	@Override
	public boolean onKeyDown(int keyCode, KeyEvent event) {
		if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
			   dialogShowOKCancel();
		}
		return false;
	}

(3)多按钮
改变了对话框的图表，添加了三个按钮

/**
* 多按钮
*/
private void dialogShowButton() {
    new AlertDialog.Builder(this)
    .setIcon(R.drawable.down)
    .setTitle("文件")
    .setMessage("请选择您的操作：")
    .setPositiveButton("保存", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            // TODO Auto-generated method stub
            Toast.makeText(TestDialogActivity.this, "保存文件", Toast.LENGTH_LONG).show();
        }
    })
    .setNegativeButton("返回", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            // TODO Auto-generated method stub
            Toast.makeText(TestDialogActivity.this, "返回继续编辑文件", Toast.LENGTH_LONG).show();
        }
    })
    .setNeutralButton("清空", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            // TODO Auto-generated method stub
            Toast.makeText(TestDialogActivity.this, "清空文件", Toast.LENGTH_LONG).show();
        }
    })
    .show();
}

	/**
	 * 多按钮
	 */
	private void dialogShowButton() {
		new AlertDialog.Builder(this)
		.setIcon(R.drawable.down)
		.setTitle("文件")
		.setMessage("请选择您的操作：")
		.setPositiveButton("保存", new DialogInterface.OnClickListener() {
			
			public void onClick(DialogInterface dialog, int which) {
				// TODO Auto-generated method stub
				Toast.makeText(TestDialogActivity.this, "保存文件", Toast.LENGTH_LONG).show();
			}
		})
		.setNegativeButton("返回", new DialogInterface.OnClickListener() {
			
			public void onClick(DialogInterface dialog, int which) {
				// TODO Auto-generated method stub
				Toast.makeText(TestDialogActivity.this, "返回继续编辑文件", Toast.LENGTH_LONG).show();
			}
		})
		.setNeutralButton("清空", new DialogInterface.OnClickListener() {
			
			public void onClick(DialogInterface dialog, int which) {
				// TODO Auto-generated method stub
				Toast.makeText(TestDialogActivity.this, "清空文件", Toast.LENGTH_LONG).show();
			}
		})
		.show();	
	}

(4)输入框
通过setView()方法，为对话框传入了一个文本编辑框，当然，你可以传入任意视图对象，如图片框。

/**
* 输入框
*/
private void dialogShowInput() {
    new AlertDialog.Builder(this)
    .setTitle("请输入")
    .setIcon(R.drawable.info)
    .setView(new EditText(this))
    .setPositiveButton("确定", null)
    .setNegativeButton("取消", null)
    .show();
}

	/**
	 * 输入框
	 */
	private void dialogShowInput() {
		new AlertDialog.Builder(this)
		.setTitle("请输入")
		.setIcon(R.drawable.info)
		.setView(new EditText(this))
		.setPositiveButton("确定", null)
		.setNegativeButton("取消", null)
		.show();
	}

上面的两个null参数，这里要放的其实是这两个按钮点击的监听程序，由于我们这里不需要监听这些动作，所以传入null值简单忽略掉，但是实际开发的时候一般都是需要传入监听器的，用来响应用户的操作。

(5)图片框

/**
* 图片框
*/
private void dialogShowImage() {
    ImageView imgView = new ImageView(this);
    imgView.setImageResource(R.drawable.image);
    new AlertDialog.Builder(this)
    .setTitle("图片框")
    .setView(imgView)
    .setPositiveButton("确定", null)
    .show();
}

	/**
	 * 图片框
	 */
	private void dialogShowImage() {
		ImageView imgView = new ImageView(this);
		imgView.setImageResource(R.drawable.image);
		new AlertDialog.Builder(this)
		.setTitle("图片框")
		.setView(imgView)
		.setPositiveButton("确定", null)
		.show();
	}

(6)单选框

/**
* 单选框
*/
private void dialogShowRadio() {
    String[] s = new String[] {"选项1", "选项2", "选项3", "选项4"};
    new AlertDialog.Builder(this)
    .setTitle("单选框")
    .setIcon(R.drawable.down)
    .setSingleChoiceItems(s, 0, new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            // TODO Auto-generated method stub
            dialog.dismiss();
        }
    })
    .setNegativeButton("取消", null)
    .show();
}

	/**
	 * 单选框
	 */
	private void dialogShowRadio() {
		String[] s = new String[] {"选项1", "选项2", "选项3", "选项4"};
		new AlertDialog.Builder(this)
		.setTitle("单选框")
		.setIcon(R.drawable.down)
		.setSingleChoiceItems(s, 0, new DialogInterface.OnClickListener() {
			
			public void onClick(DialogInterface dialog, int which) {
				// TODO Auto-generated method stub
				dialog.dismiss();
			}
		})
		.setNegativeButton("取消", null)
		.show();
	}

(7)多选框

/**
* 多选框
*/
private void dialogShowCheck() {
    String[] s = new String[] {"选项1", "选项2", "选项3", "选项4"};
    new AlertDialog.Builder(this)
    .setTitle("多选框")
    .setIcon(R.drawable.down)
    .setMultiChoiceItems(s, null, null)
    .setPositiveButton("确定", null)
    .setNegativeButton("取消", null)
    .show();
}

	/**
	 * 多选框
	 */
	private void dialogShowCheck() {
		String[] s = new String[] {"选项1", "选项2", "选项3", "选项4"};
		new AlertDialog.Builder(this)
		.setTitle("多选框")
		.setIcon(R.drawable.down)
		.setMultiChoiceItems(s, null, null)
		.setPositiveButton("确定", null)
		.setNegativeButton("取消", null)
		.show();
	}

(8)列表框

/**
* 列表框
*/
private void dialogShowList() {
    String[] s = new String[] {"列表1", "列表2", "列表3"};
    new AlertDialog.Builder(this)
    .setTitle("列表框")
    .setIcon(R.drawable.down)
    .setItems(s, null)
    .setPositiveButton("确定", null)
    .show();
}

	/**
	 * 列表框
	 */
	private void dialogShowList() {
		String[] s = new String[] {"列表1", "列表2", "列表3"};
		new AlertDialog.Builder(this)
		.setTitle("列表框")
		.setIcon(R.drawable.down)
		.setItems(s, null)
		.setPositiveButton("确定", null)
		.show();
	}
