Android对话框

对话框：提示对话框，进度条对话框，时间对话框，日期对话框

最简单对话框

AlertDialog dialog = new AlertDialog.Builder(this)
                .setIcon(R.mipmap.ic_launcher)//设置标题的图片
                .setTitle("我是对话框")//设置对话框的标题
                .setMessage("我是对话框的内容")//设置对话框的内容
                //设置对话框的按钮
                .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(Main3Activity.this, "点击了取消按钮", Toast.LENGTH_SHORT).show();
                        dialog.dismiss();
                    }
                })
                .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(Main3Activity.this, "点击了确定的按钮", Toast.LENGTH_SHORT).show();
                        dialog.dismiss();
                    }
                }).create();
        dialog.show();

时间对话框

data.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                //时间对话框
                TimePickerDialog time=new TimePickerDialog(AlertDialogActivity.this, new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

                    }
                }, h, mm,true);
                time.show();
            }
        });

日期对话框

data.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //日期对话框
                DatePickerDialog datePickerDialog=new DatePickerDialog(AlertDialogActivity.this, new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                    }
                }, year, month-1, date);
                datePickerDialog.show();

            }
        });

自定义对话框

alert_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                View view = LayoutInflater.from(AlertDialogActivity.this).inflate(R.layout.alert_item, null);
                et_name = (EditText) view.findViewById(R.id.alertitem_name);
                et_pwd = (EditText) view.findViewById(R.id.alertitem_pwd);

                AlertDialog.Builder bu = new AlertDialog.Builder(AlertDialogActivity.this);
                bu.setIcon(R.mipmap.ic_launcher);
                bu.setTitle("登录");
                bu.setView(view);
                bu.setPositiveButton("yes", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(AlertDialogActivity.this, et_name.getText().toString() + et_pwd.getText().toString(), Toast.LENGTH_SHORT).show();
                    }
                });
                bu.setNegativeButton("no", null);
                bu.show();
            }
        });

系统对话框

@Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
            AlertDialog.Builder builder=new AlertDialog.Builder(this);
            builder.setTitle("对话框");
            builder.setMessage("你确定离开吗？");
            builder.setIcon(R.mipmap.ic_launcher);
            builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {

                }
            });
            builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {

                }
            });
        }
        return super.onKeyDown(keyCode, event);
    }

进度条对话框

水平样式

progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);

圆形样式

progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);

progressDialog.setCancelable(true); // 能够返回
progressDialog.setCanceledOnTouchOutside(true); // 点击外部返回

progressDialog.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                pd=new ProgressDialog(AlertDialogActivity.this);
                pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
                pd.setMax(200);
                pd.setTitle("login");
                pd.setMessage("Do you know?");
                pd.setIcon(R.mipmap.ic_launcher);
                pd.setIndeterminate(false);
                pd.setCancelable(true);// 点击外部返回
                pd.setButton(pd.BUTTON_POSITIVE, "yes", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                    }
                });
                pd.show();

                new Thread(new Runnable() {
                    @Override
                    public void run() {
                        for (int i=0;i<=100;i++){
                            pd.setProgress(i);
                            try {
                                Thread.sleep(100);
                            } catch (InterruptedException e) {

                            }
                        }

                    }
