Question

我正在尝试创建一个应用程序来跟踪总计并通过表中包含的TextEdit显示它们。我想有几个标签来跟踪不同的表格，因此不同的总计。但是，当应用程序在模拟器上启动时，它会立即停止工作并崩溃。有谁能告诉我出了什么问题？

Android代码：

public class CounterCounterActivity extends TabActivity implements OnClickListener {
/** Called when the activity is first created. */
TextView YourLife, OppLife;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    TabHost tabHost=(TabHost)findViewById(R.id.tabHost);
    tabHost.setup();

    TabSpec spec1=tabHost.newTabSpec("Tab 1");
    spec1.setContent(R.id.tab1);
    spec1.setIndicator("Life");

    TabSpec spec2=tabHost.newTabSpec("Tab 2");
    spec2.setIndicator("+/-");
    spec2.setContent(R.id.tab2);

    TabSpec spec3=tabHost.newTabSpec("Tab 3");
    spec3.setIndicator("Poison");
    spec3.setContent(R.id.tab3);

    tabHost.addTab(spec1);
    tabHost.addTab(spec2);
    tabHost.addTab(spec3);
    tabHost.getTabWidget().getChildAt(0).getLayoutParams().height =50;
    tabHost.getTabWidget().getChildAt(1).getLayoutParams().height =50;
    tabHost.getTabWidget().getChildAt(2).getLayoutParams().height =50;
    ((Button) findViewById(R.id.button1)).setOnClickListener(this);
    ((Button) findViewById(R.id.button2)).setOnClickListener(this);
    ((Button) findViewById(R.id.button3)).setOnClickListener(this);
    ((Button) findViewById(R.id.button4)).setOnClickListener(this);
    ((Button) findViewById(R.id.button5)).setOnClickListener(this);
    ((Button) findViewById(R.id.button6)).setOnClickListener(this);
    ((Button) findViewById(R.id.button7)).setOnClickListener(this);
    ((Button) findViewById(R.id.button8)).setOnClickListener(this);
    YourLife=(TextView)findViewById(R.id.txt2);
    OppLife=(TextView)findViewById(R.id.txt1);
}
public void onClick(View view) {
    // TODO Auto-generated method stub

    Intent intent = new Intent();
    int LY=20;

        }
        if (view.getId()==R.id.button3)
        {

        }
        if (view.getId()==R.id.button4)
        {
            sel=3;

        }
        if (view.getId()==R.id.button8)
        {
            sel=4;

        }
        if (view.getId()==R.id.button5)
        {
            sel=5;

        }if (view.getId()==R.id.button2)

        switch (sel)
        {
        case 1:
        {
            LO=LO-1;
            OppLife.setText(LO);
        }
        case 2:

            OppLife.setText(LO);
        }

            LO=LO+1;
            OppLife.setText(LO);    
        }
        case 4:
        {

Answer 1

12：48：16.985：E / AndroidRuntime（331）：引起： java.lang.RuntimeException：您的内容必须有一个标识为TabHost的标签属性是'android.R.id.tabhost'

更换

android:id="@+id/tabHost"

通过

android:id="@android:id/tabHost"

应该有用。

Answer 2

由于您要在活动中扩展TabActivity，因此需要更改id的 TabHost 在您的XML中。

<TabHost android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/tabHost"
xmlns:android="http://schemas.android.com/apk/res/android"
>
