ProgressDialog
ProgressDialog基本使用说明
1. 创建ProgressDialog的两种方式
- 使用new来创建一个ProgressDialog实例
ProgressDialog dialog = new ProgressDialog(this);
dialog.show();
- 调用ProgressDialog中的静态方法show()
ProgressDialog dialog = ProgressDialog.show(this, null, "正在加载...");
静态方法show()的参数说明
public static ProgressDialog show(
Context context, // 上下文
CharSequence title, // 标题
CharSequence message, // 消息内容
boolean indeterminate, // 不确定性，false为不确定性样式，true为确定性样式
boolean cancelable, // 是否可以取消
OnCancelListener cancelListener // 取消事件监听器
);
2. 取消ProgressDialog对话框
Dialog.cancel()和Dialog.dismiss()都可以删除对话框，但是使用cancel()方法会在删除对话框时回调DialogInterface.OnCancelListener监听器中的onCancel()方法，而dismiss()则不会进行回调。
3. 设置ProgressDialog进度条样式
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); // 设置水平进度条
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); // 设置圆形旋转进度条
ProgressDialog使用示例
1. 圆形旋转进度条
private void createIndeterminateProgressDialog() {
final ProgressDialog dialog = ProgressDialog.show(this, null, "正在加载...");
new Thread(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(3000);
dialog.dismiss();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
}
效果演示

2. 水平进度条
private void createDeterminateProgressDialog() {
final ProgressDialog dialog = new ProgressDialog(this);
dialog.setIcon(R.drawable.ic_action_download); // 设置图标
dialog.setTitle("当前下载进度"); // 设置标题
dialog.setMessage("正在加载中..."); // 设置消息内容
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); // 设置水平进度条
dialog.setMax(100); // 设置最大进度值
dialog.setCancelable(true); // 设置是否可以通过点击Back键取消
dialog.setCanceledOnTouchOutside(false); // 设置在点击Dialog外是否取消Dialog进度条
dialog.setButton(DialogInterface.BUTTON_POSITIVE, "确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "确定", Toast.LENGTH_SHORT).show();
}
});
dialog.setButton(DialogInterface.BUTTON_NEUTRAL, "忽略", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "忽略", Toast.LENGTH_SHORT).show();
}
});
dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show();
}
});
// 按Back键事件监听
dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
Toast.makeText(MainActivity.this, "Cancel", Toast.LENGTH_SHORT).show();
}
});
dialog.show();
new Thread(new Runnable() {
@Override
public void run() {
int i = 0;
while (i < 100) {
try {
i += 5;
Thread.sleep(200); // 5000ms
dialog.incrementProgressBy(5); // 更新进度
} catch (InterruptedException e) {
e.printStackTrace();
}
}
try {
Thread.sleep(200);
} catch (InterruptedException e) {
e.printStackTrace();
}
dialog.dismiss();
}
}).start();
}
