无论我单击哪个文本,为什么总是看到最后一个ID? 我希望看到正确的片段显示在我根据单击的相关文本创建的布局中。我总是看到“替代品”片段。 我知道可以使用标签,但是我不知道如何使用它们。 此外,我尝试使用FragmentManager和FragmentTransaction的不同版本,甚至删除开关并分别调用textview的每个setOnClickListener,但没有帮助。
这是我的活动文件:
IngredientsFragment ingredientsFragment;
FavouritesFragment favouritesFragment;
FeedbacksFragment feedbacksFragment;
Write_Feedback_Fragment writeFeedbackFragment;
AlternativesFragment alternativesFragment;
TextView ingredients;
TextView favourites;
TextView feedbacks;
TextView alternatives;
TextView writeFeedback;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_product_details);
window=this.getWindow();
window.setStatusBarColor(this.getResources().getColor(R.color.colorPrimaryDark));
ingredients= (TextView) findViewById(R.id.ingredients_option);
favourites= (TextView) findViewById(R.id.favorites_option);
feedbacks= (TextView) findViewById(R.id.watch_feedback_option);
writeFeedback= (TextView) findViewById(R.id.add_feedback_option);
alternatives= (TextView) findViewById(R.id.alternatives_option);
ingredients.setOnClickListener(this);
favourites.setOnClickListener(this);
feedbacks.setOnClickListener(this);
writeFeedback.setOnClickListener(this);
alternatives.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.ingredients_option:
ingredientsFragment= new IngredientsFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,ingredientsFragment).commit();
break;
case R.id.favorites_option:
favouritesFragment= new FavouritesFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,favouritesFragment).commit();
break;
case R.id.watch_feedback_option:
feedbacksFragment= new FeedbacksFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,feedbacksFragment).commit();
break;
case R.id.add_feedback_option:
writeFeedbackFragment= new Write_Feedback_Fragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,writeFeedbackFragment).commit();
break;
case R.id.alternatives_option:
alternativesFragment= new AlternativesFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,alternativesFragment).commit();
break;
}
}
}

答案 0 :(得分:0)
您的代码应该这样工作。问题是您的布局。在FrameLayout中查看textviews。您定义paddingLeft和layout_width,以便您的textview Alternatives_option覆盖所有其他textview。这就是为什么在onclick中总会获得该视图的ID。
我建议编写有关XML布局的教程。
<TextView
android:id="@+id/alternatives_option"
android:layout_width="408dp"
android:layout_height="90dp"
android:layout_gravity="left"
android:drawableTop="@drawable/ic_alternatives"
android:paddingLeft="320dp"
android:text="Alternatives" />
