祝酒词会保留很长时间

Question

我想在搜索后找不到结果时显示Toast，我做了一个简单的吐司，但吐司会保留很长时间，我希望它在短时间后消失

这是代码

public boolean onQueryTextSubmit(String query) {
final String[] dose = getResources().getStringArray(R.array.doses);
final String[] use = getResources().getStringArray(R.array.uses);
final String[] composition = getResources().getStringArray(R.array.composition);

final TypedArray img  = getResources().obtainTypedArray(R.array.img);
for (String search : suggestions)
{
if (query.equals(search)){
for (int i =0; i<suggestions.length; i++){
if (query.equals(suggestions[i])){
Intent intent = new Intent(MainActivity.this,productDetails.class);
int im = img.getResourceId(i,-1);
intent.putExtra("img",im);
intent.putExtra("dose",dose[i]);
intent.putExtra("use",use[i]);
intent.putExtra("composition",composition[i]);
intent.putExtra("title",suggestions[i].toUpperCase());
startActivity(intent);
}
}
}
else if (query!= search){
Toast.makeText(MainActivity.this, "No Results Found", Toast.LENGTH_SHORT).show();

}
}
return false;
}

您的toast显示在for循环中，他多次被添加到队列中，将其从循环中删除
