进度对话框未显示
进度对话框未显示

用于显示进度对话框的以下代码，
public void showDialog() {
try {
Log.d(TAG, "showDialog--------------");
progressDialog = new Dialog(RewardsActivity.this);
final View dialogView = LayoutInflater.from(RewardsActivity.this).inflate(R.layout.progress_dialog, null);
progressDialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
progressDialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
progressDialog.setContentView(dialogView);
progressDialog.setCancelable(true);
final ImageView progressSpinner = (ImageView) dialogView.findViewById(R.id.ivProgress);
final RotateAnimation anim = new RotateAnimation(0f, 350f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
anim.setRepeatCount(Animation.INFINITE);
anim.setDuration(500);
anim.setInterpolator(new LinearInterpolator());
progressSpinner.startAnimation(anim);
progressDialog.show();
Log.d(TAG, "showDialog--------------");
progressDialog.getWindow().setLayout(120, 120);
} catch (Exception e) {
}
}在Activity类的onCreate中调用showDialog
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rewards);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
tinyDB = new TinyDB(getApplicationContext());
showDialog();
new GetRewardsResponse(getApplicationContext(), this, tinyDB);
viewpager = (ViewPager) findViewById(R.id.viewPager);
indicator = (CircleIndicator) findViewById(R.id.indicator);
indicator.setViewPager(viewpager);
if (progressDialog.isShowing()) {
progressDialog.hide();
}
}在调试时，showDaialog方法被完全执行(对话框不可见)，但当应用程序运行时，它不会执行showDialog，因为我在安卓监视器中看不到我的日志语句

尝尝这个
public void showDialog() {
try {
Log.d(TAG, "showDialog--------------");
progressDialog = new Dialog(RewardsActivity.this);
final View dialogView = LayoutInflater.from(RewardsActivity.this).inflate(R.layout.progress_dialog, null);
progressDialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
progressDialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
progressDialog.setContentView(dialogView);
progressDialog.setCancelable(true);
final ImageView progressSpinner = (ImageView) dialogView.findViewById(R.id.ivProgress);
final RotateAnimation anim = new RotateAnimation(0f, 350f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
anim.setRepeatCount(Animation.INFINITE);
anim.setDuration(500);
anim.setInterpolator(new LinearInterpolator());
progressSpinner.startAnimation(anim);
progressDialog.show();
Log.d(TAG, "showDialog--------------");
} catch (Exception e) {
}
}还要从oncreate中删除此行。
if (progressDialog.isShowing()) {
progressDialog.hide();

删除下面的代码行或延迟一些时间来隐藏progressDialog，因为showDialog()正在显示对话框，但它突然关闭了。
if (progressDialog.isShowing()) {
progressDialog.hide();

我对你的代码做了一些修改。
private Context mContext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rewards);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
tinyDB = new TinyDB(getApplicationContext());
showDialog();
new GetRewardsResponse(getApplicationContext(), this, tinyDB);
viewpager = (ViewPager) findViewById(R.id.viewPager);
indicator = (CircleIndicator) findViewById(R.id.indicator);
indicator.setViewPager(viewpager);
if (progressDialog.isShowing()) {
progressDialog.hide();
}
}
public void showDialog() {
try {
Log.d(TAG, "showDialog--------------");
LayoutInflater inflater = getLayoutInflater();
progressDialog = new Dialog(mContext);
final View dialogView = inflater.inflate(R.layout.progress_dialog, null);
progressDialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
progressDialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
progressDialog.setContentView(dialogView);
progressDialog.setCancelable(true);
final ImageView progressSpinner = (ImageView) dialogView.findViewById(R.id.ivProgress);
final RotateAnimation anim = new RotateAnimation(0f, 350f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
anim.setRepeatCount(Animation.INFINITE);
anim.setDuration(500);
anim.setInterpolator(new LinearInterpolator());
progressSpinner.startAnimation(anim);
progressDialog.getWindow().setLayout(120, 120);
progressDialog.show();
Log.d(TAG, "showDialog--------------");
} catch (Exception e) {
}
