我正在嘗試從火庫中獲取圖像。因此，當(dāng)firebase中沒有圖像時(shí)，我希望我的應(yīng)用程序徽標(biāo)將設(shè)置在那里。但我的應(yīng)用程序正在崩潰并將錯(cuò)誤扔進(jìn)日志貓。我嘗試使用如果-否則條件。以及成功和錯(cuò)誤方法。但工作不正常。private static final String Earnings_Freebies = "EARNINGS_FREEBIES"; private Earnings_Freebies list; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.earnings_freebies);list = (Earnings_Freebies) getIntent().getExtras().getSerializable(Earnings_Freebies); if (TextUtils.isEmpty(list.getmImageView())){ m_EF_ImageView.setImageResource(R.drawable.app_logo); mProgressBarEF.setVisibility(View.GONE); } Picasso.with(getApplicationContext()) .load(list.getmImageView()) .into(m_EF_ImageView, new Callback() { @Override public void onSuccess() { mProgressBarEF.setVisibility(View.GONE); mFailedImage.setVisibility(View.GONE); } @Override public void onError() { mProgressBarEF.setVisibility(View.GONE); mFailedImage.setVisibility(View.VISIBLE); } });我想要當(dāng)有錯(cuò)誤?；蛘呶彝泴D像放入firebase，然后應(yīng)用程序徽標(biāo)將自動(dòng)設(shè)置為圖像視圖。

您可以嘗試以下代碼。如果沒有幫助，請讓我更多地了解Earnings_Freebies模型。
確保您使用的是畢加索的最新依賴項(xiàng)。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.earnings_freebies);
list = (Earnings_Freebies) getIntent().getExtras().getSerializable(Earnings_Freebies);
if (list == null && TextUtils.isEmpty(list.getmImageView())){
m_EF_ImageView.setImageResource(R.drawable.app_logo);
mProgressBarEF.setVisibility(View.GONE);
Picasso.with(getApplicationContext())
.load(R.mipmap.ic_launcher) // can also be a drawable
.into(m_EF_ImageView);
} else {
Picasso.with(getApplicationContext())
.load(list.getmImageView())
.placeholder(R.mipmap.ic_launcher) // can also be a drawable
.into(m_EF_ImageView);
}
}

你可以試試這種方式：
private static final String Earnings_Freebies = "EARNINGS_FREEBIES";
private Earnings_Freebies list;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.earnings_freebies);
list = (Earnings_Freebies) getIntent().getExtras().getSerializable(Earnings_Freebies);
if (list != null && list.getmImageView() != null && !TextUtils.isEmpty(list.getmImageView())){
Picasso.with(getApplicationContext())
.load(list.getmImageView())
.into(m_EF_ImageView, new Callback() {
@Override
public void onSuccess() {
mProgressBarEF.setVisibility(View.GONE);
mFailedImage.setVisibility(View.GONE);
}
@Override
public void onError() {
mProgressBarEF.setVisibility(View.GONE);
mFailedImage.setVisibility(View.VISIBLE);
}
});
}else{
Picasso.with(getApplicationContext())
.load(R.drawable.app_logo)
.placeholder(R.drawable.app_logo)
.into(m_EF_ImageView);
}
}

1）畢加索支持下載占位符和錯(cuò)誤占位符作為可選功能。
2）如果加載圖像失敗，將使用錯(cuò)誤可繪制。在這種情況下，臨時(shí)占位符圖像將被放置在 .error（） 方法中的錯(cuò)誤可繪制圖像替換，你可以在其中顯示應(yīng)用的圖標(biāo)圖像，以防出現(xiàn)錯(cuò)誤。
Picasso.with(this).load("https://someImageURL")
.error(R.mipmap.ic_launcher) // Your app's icon image displayed on error
.placeholder(R.drawable.user_placeholder) // some placeholder image
.into(imageView, new Callback() {
@Override
public void onSuccess() {
Log.d("TAG", "onSuccess");
}
@Override
public void onError() {
Toast.makeText(getApplicationContext(), "An error occurred", Toast.LENGTH_SHORT).show();
}
});
