showDialog（）でメッセージを表示する方法。ダウンロード表示してポップアップメッセージを表示
freshDownloadViewが終了したらshow showDialogを表示します。次のように
私のコードは次のとおりです。
public class MainActivity extends Activity implements View.OnClickListener {
private FreshDownloadView freshDownloadView;
private Button btDownloaded;
private TextView btReset;
private TextView btDownloadError;
private final int FLAG_SHOW_OK = 10;
private final int FLAG_SHOW_ERROR = 11;
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
int progress = (int) msg.obj;
freshDownloadView.upDateProgress(progress);
switch (msg.what) {
case FLAG_SHOW_OK:
break;
case FLAG_SHOW_ERROR:
freshDownloadView.showDownloadError();
break;
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
freshDownloadView = (FreshDownloadView) findViewById(R.id.pitt);
btDownloaded = (Button) findViewById(R.id.bt_downloaded);
btReset = (Button) findViewById(R.id.bt_reset);
btDownloadError = (Button) findViewById(R.id.bt_download_error);
btDownloaded.setOnClickListener(this);
btReset.setOnClickListener(this);
btDownloadError.setOnClickListener(this);
}
これは、私はあなたがこのためにAsyncTaskを使用することをお勧めボタンfreshDownload
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.bt_downloaded:
if (freshDownloadView.using()) return;
new Thread(new Runnable() {
@Override
public void run() {
for (int i = 0; i <= 100; i++) {
try {
Thread.sleep(50);
} catch (InterruptedException e) {
e.printStackTrace();
}
Message message = Message.obtain();
message.obj = i;
handler.sendMessage(message);
showDialog();
}
}

break;

freshDownloadView.reset();
break;
