Android学习笔记（九）——更复杂的进度对话框

<Button
android:id="@+id/btn_dialog3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="onClick3"
android:text="Click to display a detailed progress dialog" />

public void onClick3(View v) {
showDialog(1);// id为1，在调用回调方法onCreateDialog()时。将id传进去。使其选择case 1情况。
progressDialog.setProgress(0);// 从0開始

new Thread(new Runnable() {

@Override
public void run() {
// TODO Auto-generated method stub
for (int i = 1; i <= 10; i++) {
try {
Thread.sleep(1000);
progressDialog.incrementProgressBy(100 / 10);// 步进为10
} catch (InterruptedException e) {
// TODO: handle exception
e.printStackTrace();
}
}
progressDialog.dismiss();// 销毁对话框
}
}).start();
}

case 1:
progressDialog = new ProgressDialog(this);
progressDialog.setIcon(R.drawable.ic_launcher);
progressDialog.setTitle("Downloading files...");
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);// 设置进度条样式
progressDialog.setButton(DialogInterface.BUTTON_POSITIVE, "OK",// 设置OKbutton
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "OK clicked!",
Toast.LENGTH_SHORT).show();
}
});
progressDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel",// 设置取消button
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "Cancel clicked!",
Toast.LENGTH_SHORT).show();
}
