android自定义tabhost,tabcontent用intent获得

地址：http://my.oschina.net/aowu/blog/36282

自己改的自定义tabhost组建，效果图如左。有更好的朋友可以相互交流一下，嘿嘿。

1.先上AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.priscilla"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="7" />

    <application
        android:icon="@drawable/icon"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".MyTab" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".TabContent" >
        </activity>
    </application>

</manifest>

  // 设置当前显示哪一个标签

   mTabSpec.add(mTabhost.newTabSpec("tab" + i));
   linearLayout.add((LinearLayout) mInflater.inflate(
     R.layout.tabwidget, null));
   mtext.add((TextView) linearLayout.get(i)
     .findViewById(R.id.tab_name));

   Log.v("---whty---", mTabSpec.get(i).getTag());
   Bundle buddle = new Bundle();

  }
 }

  super.onCreate(savedInstanceState);
  setContentView(R.layout.tabcontent);

  textView = (TextView) findViewById(R.id.TextView);
  imgView = (ImageView) findViewById(R.id.ImageView);

  Bundle buddle = this.getIntent().getExtras();
  String flag = buddle.getString("tab");

  if ("tab0".equals(flag)) {
   textView.setText(getResources().getString(R.string.andy));
   Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
     R.drawable.andy);
   imgView.setImageBitmap(bitmap);
  }

  if ("tab1".equals(flag)) {

  if ("tab2".equals(flag)) {
   textView.setText(getResources().getString(R.string.linux));
   Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
     R.drawable.torvalds);
   imgView.setImageBitmap(bitmap);
  }

 }

}
