右我有一個主要的佈局定義，有一個框架，在該框架中的表，然後在底部水平滾動視圖與加載按鈕。單擊按鈕時，框架的內容應更改爲新表格，就像在選項卡布局教程中選擇不同的選項卡時一樣（不使用選項卡布局，因爲我有許多按鈕不適合在屏幕上，除非滾動）更改按鈕單擊框架佈局的內容

現在對於標籤更改選項卡的內容似乎很容易，像這樣：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, ArtistsActivity.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_artists))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, AlbumsActivity.class);
spec = tabHost.newTabSpec("albums").setIndicator("Albums",
res.getDrawable(R.drawable.ic_tab_albums))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, SongsActivity.class);
spec = tabHost.newTabSpec("songs").setIndicator("Songs",
res.getDrawable(R.drawable.ic_tab_songs))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(2);
}
我怎樣才能做到與框架內容和按鈕類似的東西？我正在考慮沿線的東西
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
final Intent batchingIntent, mergingIntent, processingIntent;
// Create an Intent to launch an Activity for the tab (to be reused)
final Button batchButton = (Button) findViewById(R.id.batching);
batchingIntent = new Intent().setClass(this, BatchingActivity.class);
batchButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
FrameLayout frame = (FrameLayout) findViewById(R.id.tabcontent);
frame.setContent(batchingIntent) // doesn't exist obviously
}
});
