错误：“您需要指定一种创建Tab指标的方法”(Error: “You need to specify a way to create Tab indicator”)

我正在创建一个TabHost，它是一个片段中的Tab视图。子片段将连接到名为fragment_usage主fragment_usage 。运行后，它一直给我这个错误：

您需要指定一种创建选项卡指示器的方法。

I am creating a TabHost which is a Tab view in a fragment. The sub fragment will be connected to my main fragment called fragment_usage. After running, it keeps giving me this error:

you need to specify a way to create tab indicator.

最满意答案

更改spec1-> spec2，spec3，spec4 ; 复制时要小心:)

TabHost.TabSpec spec1 = tab.newTabSpec("Tab 1"); spec1.setIndicator("Tab 1"); spec1.setContent(R.id.Tab1); tab.addTab(spec1); TabHost.TabSpec spec2 = tab.newTabSpec("Tab 2"); spec2 .setIndicator("Tab 2"); spec2 .setContent(R.id.Tab2); tab.addTab(spec2); TabHost.TabSpec spec3 = tab.newTabSpec("Tab 3"); spec3 .setIndicator("Tab 3"); spec3 .setContent(R.id.Tab3); tab.addTab(spec3); TabHost.TabSpec spec4 = tab.newTabSpec("Tab 4"); spec4 .setIndicator("Tab 4"); spec4 .setContent(R.id.Tab4); tab.addTab(spec4);

Change spec1-> spec2,spec3,spec4; Be careful when you are copying :)

TabHost.TabSpec spec1 = tab.newTabSpec("Tab 1"); spec1.setIndicator("Tab 1"); spec1.setContent(R.id.Tab1); tab.addTab(spec1); TabHost.TabSpec spec2 = tab.newTabSpec("Tab 2"); spec2 .setIndicator("Tab 2"); spec2 .setContent(R.id.Tab2); tab.addTab(spec2); TabHost.TabSpec spec3 = tab.newTabSpec("Tab 3"); spec3 .setIndicator("Tab 3"); spec3 .setContent(R.id.Tab3); tab.addTab(spec3); TabHost.TabSpec spec4 = tab.newTabSpec("Tab 4"); spec4 .setIndicator("Tab 4"); spec4 .setContent(R.id.Tab4); tab.addTab(spec4);
