我有一个应用程序,我的设计有2个标签。 Tab1有listview,我想点击每个listitem给出一个细节。但是在项目的选项上,标签设计和Tab2数据和设计必须保持一致。那么我可以用相同的设计开始新的意图吗?如果是,应该复制设计代码,或者我应该为Tab View设计和每个Tab ??
单独制作类或者有没有办法可以更新标签1的视图?而且,如果我更新tab1的视图将按下后退按钮将用户带到以前的视图或启动我的应用程序???
代码:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.activity_main);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
TabHost tabhost=(TabHost) findViewById(R.id.tabHost);
tabhost.setup();
tabhost.getTabWidget().setDividerDrawable(R.drawable.divider2);
TabSpec spec1=tabhost.newTabSpec("Tab 1");
spec1.setContent(R.id.tab1);
spec1.setIndicator("Tab 1");
TabSpec spec2=tabhost.newTabSpec("Tab 2");
spec2.setIndicator("Tab 2");
spec2.setContent(R.id.tab2);
tabhost.addTab(spec1);
tabhost.addTab(spec2);
tabhost.getTabWidget().getChildTabViewAt(0).setBackgroundDrawable(null);
tabhost.getTabWidget().getChildTabViewAt(1).setBackgroundDrawable(null);
String values[]={"Apple", "IOS", "Google", "Android"};
ListView listview=(ListView) findViewById(R.id.listview);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, R.layout.listviewstyle,R.id.textlist, values);
//ArrayAdapter<String> adapter2=new ArrayAdapter<String>(this, R.id.textlist2);
listview.setAdapter(adapter);
listview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
//I want to update Tab1 now using this function and change into a completely new layout
TextView tv=(TextView) findViewById(R.id.frame2text);
tv.setText(data);
frm1=(FrameLayout) findViewById(R.id.frame1);
frm2=(FrameLayout) findViewById(R.id.frame2);
frm1.setVisibility(View.GONE);
frm2.setVisibility(View.VISIBLE);
islast=true;
}
});
}

根据您的需要更新ArrayList
,并使用notifydatasetchanged()
for tab1更新列表项。
答案 1 :(得分:0)
Hello Brooklyn你的列表项目点击工作正常。
解决您必须使用的问题
TabGroupActivity扩展了ActivityGroup
在同一个标签下处理多项活动。
您可以浏览here
或者您可以使用标签here
查看其他方式的片段
我希望它可以帮到你。
答案 2 :(得分:0)
使用您想要的新布局在相同的xml中创建另一个FrameLayout。 将framelayout可见性设置为GONE。
现在点击列表视图项目的第二个framelayout的setvisibility是可见的,第一个framelayout是GONE。
使用此
更新上述代码FrameLayout fm1,fm2;
boolean islast;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.activity_main);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
TabHost tabhost=(TabHost) findViewById(R.id.tabHost);
tabhost.setup();
tabhost.getTabWidget().setDividerDrawable(R.drawable.divider2);
TabSpec spec1=tabhost.newTabSpec("Tab 1");
spec1.setContent(R.id.tab1);
spec1.setIndicator("Tab 1");
TabSpec spec2=tabhost.newTabSpec("Tab 2");
spec2.setIndicator("Tab 2");
spec2.setContent(R.id.tab2);
tabhost.addTab(spec1);
tabhost.addTab(spec2);
tabhost.getTabWidget().getChildTabViewAt(0).setBackgroundDrawable(null);
tabhost.getTabWidget().getChildTabViewAt(1).setBackgroundDrawable(null);
String values[]={"Apple", "IOS", "Google", "Android"};
fm1 = (FrameLayout) findViewById(R.id.fm1);
fm2 = (FrameLayout) findViewById(R.id.fm2);
ListView listview=(ListView) findViewById(R.id.listview);
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, R.layout.listviewstyle,R.id.textlist, values);
//ArrayAdapter<String> adapter2=new ArrayAdapter<String>(this, R.id.textlist2);
listview.setAdapter(adapter);
listview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
//I want to update Tab1 now using this function and change into a completely new layout
Toast.makeText(MainActivity.this,"ITEM CLICK", Toast.LENGTH_SHORT).show();
fm1.setVisibility(View.GONE);
fm2.setVisibility(View.VISIBLE);
islast = true;
}
});
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
if (islast) {
fm1.setVisibility(View.VISIBLE);
fm2.setVisibility(View.GONE);
islast = false;
startActivity(new Intent(MainActivity.this,MainActivity.class));
}else {
finish();
}
}
}
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:paddingTop="60dp"
android:id="@+id/tab1">
//Update HERE below given code
</LinearLayout>
使用以下代码更新tab1的线性布局。
<FrameLayout
android:id="@+id/fm1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:dividerHeight="10dp"
android:paddingTop="15dp"
android:smoothScrollbar="true" />
</FrameLayout>
<FrameLayout
android:id="@+id/fm2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="gone" >
<TextView
android:id="@+id/txt1"
android:layout_width="fill_parent"
android:layout_height="50dp" />
</FrameLayout>
