我想在进度条达到100%后显示另一条警告消息(警告框/警告对话框)。我怎么做?
还有什么方法可以设置那个盒子(或两个盒子)的样式?
以下是我的ProgressBar代码:
public class MainActivity extends Activity {
Button progress_button;
ProgressDialog pro_dialog;
Handler pro_handler;
int progress;
private static final int MAX_PROGRESS = 100;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
// intiliazing the buttons
progress_button = (Button) findViewById(R.id.button1);
progress_button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// Creating progress dialog interface setting
// title,progressstyle,max_progress
pro_dialog = new ProgressDialog(MainActivity.this);
pro_dialog.setTitle("Making everything OK is in progress! Please be patient.");
pro_dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pro_dialog.setMax(MAX_PROGRESS);
progress = 0;
pro_dialog.show();
pro_dialog.setProgress(0);
pro_handler.sendEmptyMessage(0);
}
});
// set onclick listener for buttons
pro_handler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
if (progress >= MAX_PROGRESS) {
pro_dialog.dismiss();
} else {
progress++;
pro_dialog.incrementProgressBy(2);
pro_handler.sendEmptyMessageDelayed(0, 100);
}
}
};
}
答案 0 :(得分:0)
首先,如果你可以替换它会更有意义:
pro_dialog.incrementProgressBy(2);
用这个:
pro_dialog.setProgress(progress);
当前代码在进度变量达到MAX_PROGRESS后解除对话框,但进度对话框不显示此变量的当前值。
如果您想显示AlertDialog,您可以在“pro_dialog.dismiss()”之后执行此操作。
