ProgressDialog常用属性

dialog.hide() //隐藏 dialog.cancel(); //销毁+回调dialog.show(); //显示 dialog.dismiss(); //正常关闭

dialog.setIcon(R.drawable.app_icon); //图标 dialog.setTitle("提示"); dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); 风格1-圆形旋转进度条 dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);风格2-水平进度条

实例1-带旋转动画的等待窗口 (高版本已经放弃)

ProgressDialog dialog = new ProgressDialog(context); dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); dialog.setMessage("请稍等..."); // 设置ProgressDialog 提示信息 dialog.setIndeterminate(false); // 设置ProgressDialog 的进度条是否不明确 dialog.setCancelable(false); // 设置ProgressDialog 是否可以按退回按键取消 dialog.show(); // 设置对话框大小 Window window = dialog.getWindow(); if (window != null) { WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams(); layoutParams.copyFrom(window.getAttributes()); // 设置宽度和高度（单位：像素） layoutParams.width = 400; // 宽度 layoutParams.height = 120; // 高度 // 或者使用 DP 单位（推荐） // layoutParams.width = (int) (300 * getResources().getDisplayMetrics().density); // layoutParams.height = (int) (200 * getResources().getDisplayMetrics().density); window.setAttributes(layoutParams); }

实例2-带旋转动画的等待窗口 （推荐）

RotateLoadingDialog dialog = new RotateLoadingDialog(); dialog.show(context, "数据导出中..."); dialog.hide();// 关闭对话框

import android.app.AlertDialog; import android.content.Context; import android.widget.ProgressBar; public class RotateLoadingDialog { private AlertDialog dialog; public void show(Context context, String message) { ProgressBar pb = new ProgressBar(context); pb.setPadding(50, 0, 50, 20); dialog = new AlertDialog.Builder(context) .setMessage(message) .setView(pb) .setCancelable(false) .create(); dialog.show(); } public void hide() { if (dialog != null && dialog.isShowing()) { dialog.dismiss(); } } }

实例3-带旋转动画的等待窗口 ( 取消 确定稍后提醒)

ProgressDialog dialog = new ProgressDialog(context); dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); dialog.setMessage("请稍等..."); // 设置ProgressDialog 提示信息 dialog.setIndeterminate(false); // 设置ProgressDialog 的进度条是否不明确 dialog.setCancelable(false); // 设置ProgressDialog 是否可以按退回按键取消 dialog.setButton(DialogInterface.BUTTON_NEGATIVE,"稍后提醒", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Log.e(TAG, "onClick: 稍后提醒"); } }); dialog.setButton(DialogInterface.BUTTON_NEUTRAL,"取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // 取消按钮的点击事件 dialog.dismiss(); Log.e(TAG, "onClick: 取消"); } }); dialog.setButton(DialogInterface.BUTTON_POSITIVE,"确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Log.e(TAG, "onClick: 确定"); } }); dialog.show();

实例3-水平进度条

final ProgressDialog pd2 = new ProgressDialog(context); pd2.setTitle(" 蓝牙搜索中..."); pd2.setIcon(R.mipmap.ic_launcher_round); pd2.setCancelable(false); //点击进度条以外，进度条消失 pd2.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); pd2.setMax(100); pd2.show(); new Thread(new Runnable() { @Override public void run() { try { for (int i = 0; i <= 100; i++){ pd2.setProgress(i); Thread.sleep(100); } pd2.cancel(); } catch (InterruptedException e) { e.printStackTrace(); } } }).start();
