我有一个活动,它在视图寻呼机中托管两个片段。我使用相同的布局来夸大这些碎片。布局有两个编辑文本放置在线性布局内,该布局位于相对布局内。问题是当我从片段A切换到片段B时,他首先编辑文本在片段A中有焦点,当我从片段B返回到片段A时,而不是第一个具有焦点的编辑文本,第二个编辑文本获得焦点。如何解决它。我提供下面的布局和源代码。我没有在片段类中返回任何代码。
活动:
public class LoginActivity extends BaseActivity {
public static final String selectedTabPosition = "selectedTabPosition";
//Tab tag name
private static String TAB_1_TAG = "Email";
private static String TAB_2_TAG = "Mobile";
private TabLayout mTabLayout;
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
TAB_1_TAG = getResources().getString(R.string.tab_email);
TAB_2_TAG = getResources().getString(R.string.tab_mobile);
//Initialise views
mViewPager = (ViewPager) findViewById(R.id.viewpager);
mTabLayout = (TabLayout) findViewById(R.id.tabs);
//set tab with view pager
setupViewPager(mViewPager);
mTabLayout.setupWithViewPager(mViewPager);
setupTabIcons();
mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
dismissKeyboard(mViewPager);
}
@Override
public void onPageScrollStateChanged(int state) {
}
});

将requestFocus
属性用于您的第一个editText
,这将始终使该editText获得焦点。
在fragment_login.xml
文件中进行以下更改
<EditText
android:id="@+id/et_email"
android:layout_width="match_parent"
android:layout_height="@dimen/spacing_48">
<requestFocus />
</EditText>
答案 1 :(得分:0)
您可以在片段运行时禁用焦点EditText
:
EditText et_email_view = (EditText) rootView.findViewById(R.id.et_email);
et_email_view.setFocusable(false);
答案 2 :(得分:0)
例如在我的情况下,viewPager覆盖了editText。我在editText(translationZ
)和viewPage(translationZ="2"
)设置translationZ="1"
,它帮助了我。
