[英]android: can't display indicator text and drawable on tabhost
我正在嘗試用四個選項卡選項卡在android中做一個簡單的選項卡應用程序。 我的問題是,當我想顯示圖標和指示器時,它僅顯示文本指示器,我想在tabhost上顯示可繪制和指示器文本,這是我的代碼:
@Override
protected void onCreate(Bundle savedInstanceState) {
//hide title bar
BasicDisplaySettings.toggleTaskBar(SimasCardMainActivity.this, false);
//show status bar
BasicDisplaySettings.toggleStatusBar(SimasCardMainActivity.this, true);
super.onCreate(savedInstanceState);
setContentView(R.layout.simascard);
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, TerbaruSimasCard.class);
spec = tabHost.newTabSpec("Terbaru").setIndicator("Terbaru",
res.getDrawable(R.drawable.menu_terbaru))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, MerchantSimasCard.class);
spec = tabHost.newTabSpec("Merchant").setIndicator("Merchant",
res.getDrawable(R.drawable.menu_merchant))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, TentangSimasCard.class);
spec = tabHost.newTabSpec("Tentang").setIndicator("Tentang",
res.getDrawable(R.drawable.menu_tentang))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, FaqSimasCard.class);
spec = tabHost.newTabSpec("FAQ").setIndicator("FAQ",
res.getDrawable(R.drawable.menu_faq))
.setContent(intent);
tabHost.addTab(spec);
for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++){
tabHost.getTabWidget().getChildAt(i).setPadding(0,0,0,0);
tabHost.getTabWidget().getChildTabViewAt(i).setBackgroundDrawable(null);
}
tabHost.setCurrentTab(0);
}
// @Override
public void onBackPressed() {
finish();
}
當我使用
spec = tabHost.newTabSpec("Tentang").setIndicator("",
res.getDrawable(R.drawable.menu_tentang))
.setContent(intent);
它會顯示一個圖標,但是當我在setIndicator
上setIndicator
諸如setIndicator("Tentang")
之類的文本時,它僅在tabhost上顯示指示符文本,我不知道我的代碼在哪里出問題,我試圖增加標簽高度,但是不起作用,我希望有人可以幫助我解決問題。 謝謝
刪除此tabHost.getTabWidget().getChildTabViewAt(i).setBackgroundDrawable(null);
並替換為
tabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.menu_tentang);
我已經做到了,它工作正常
Resources ressources = getResources();
TabHost tabHost = getTabHost();
Intent addfriend = new Intent().setClass(this, yourclass1.class);
Intent mailfriend = new Intent().setClass(this, yourclass2.class);
tabHost.addTab(tabHost.newTabSpec("child1").setIndicator("your tag",getResources().getDrawable(R.drawable.youpng)).setContent(addfriend));
tabHost.addTab(tabHost.newTabSpec("child1").setIndicator("your tag",getResources().getDrawable(R.drawable.yourpng)).setContent(mailfriend));
tabHost.getTabWidget().getChildAt(0).setBackgroundColor(getResources().getColor(R.color.anycolor));
tabHost.getTabWidget().getChildAt(0).setBackgroundResource(R.drawable.yourpng);
tabHost.getTabWidget().getChildAt(1).setBackgroundColor(getResources().getColor(R.color.anycolor));
tabHost.getTabWidget().getChildAt(1).setBackgroundResource(R.drawable.youpng);
