タブホストを xml に追加するときに使用しようとしていますが、正しくないようです。Java で行う必要があることがあると思います。3 つの異なるクラスで 3 つのタブを設定しようとしていますが、これは可能ですか? ?
ここに私のxmlがあります:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TabHost
android:id="@android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TabWidget
android:id="@android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TabWidget>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="@+id/tab1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Browser History:"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="@+id/hello"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:id="@+id/tab2"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Call Log"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="@+id/call"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:id="@+id/tab3"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text Messages"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="@+id/tvSms"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</FrameLayout>
</LinearLayout>
</TabHost>
</LinearLayout>
</LinearLayout>
また、各タブを使用して各アクティビティを開こうとしているため、3 つの異なるクラスがあります。
クラスはこちら
package com.johnnydicamillo.spybeta;
import android.app.Activity;
import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.Browser;
import android.widget.TabHost;
import android.widget.TextView;
public class AndroidSpybetaActivity extends TabActivity {
/** Called when the activity is first created. */
Resources res;
TabHost tabHost;
Intent intent;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
res = getResources();
tabHost = getTabHost();
TabHost.TabSpec spec;
intent = new Intent().setClass(this, Messaging.class);
spec = tabHost.newTabSpec("messaging").setIndicator("Messaging")
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, TestingData.class);
spec = tabHost.newTabSpec("Calls").setIndicator("Calls")
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(0);
TextView view = (TextView) findViewById(R.id.hello);
Cursor mCur = managedQuery(android.provider.Browser.BOOKMARKS_URI,
null, null, null, null);
mCur.moveToFirst();
int index = mCur.getColumnIndex(Browser.BookmarkColumns.TITLE);
while (mCur.isAfterLast() == false) {
view.append(" WebSite " + mCur.getString(index));
mCur.moveToNext();
}
}
}
2番
package com.johnnydicamillo.spybeta;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class Messaging extends TabActivity{
static TextView messageBox;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
messageBox = (TextView) findViewById(R.id.tvSms);
}
public static void updateMessageBox(String msg) {
messageBox.append(msg);
}
}
そして3番目
package com.johnnydicamillo.spybeta;
import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.CallLog;
import android.provider.CallLog.Calls;
import android.widget.TextView;
public class TestingData extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView view = (TextView) findViewById(R.id.call);
String[] projection = new String[] {
Calls.NUMBER
};
Cursor mCur = managedQuery(CallLog.Calls.CONTENT_URI, projection,
Calls.DURATION + "<?", new String[] { "60" }, Calls.DURATION
+ " ASC");
mCur.moveToFirst();
while (mCur.isAfterLast() == false) {
for (int i = 0; i < mCur.getColumnCount(); i++) {
view.append(" Number " + mCur.getString(i));
}
mCur.moveToNext();
}
}
}
これが私のlogcatです:
