您错误地初始化了TextView因为您在布局中添加了TextView ，并且尝试使用LinearLayout初始化它，这是错误的。
使用onCreate（）中的TextView更改LinearLayout ，如下所示：
someLayout = (TextView) findViewById(R.id.state2);
为什么要在代码中两次夸大布局？ 我不明白你为什么这样做。 但我提供代码与一些相关的代码尝试我的代码。
public class MainActivity extends Activity { private LayoutInflater inflater; private TextView someLayout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); someLayout = (TextView) findViewById(R.id.state2); //layout present in activity_main // inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE); runNextTask(); } public void runNextTask(){ // LinearLayout mInflatedLayout = (LinearLayout) inflater.inflate(R.layout.activity_main, null); @SuppressWarnings("unused") final TrackerInfo newInfo = new TrackerInfo(); //set up for model selection // TextView modelTextview = (TextView)mInflatedLayout.findViewById(R.id.state2); //someLayout.addView(mInflatedLayout); someLayout.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { } }); }
仅供参考你不能在TextView添加任何布局，因为它的View不是Layout ，在你的代码中我看到你试图将Layout添加到View这是错误的。
您的线性布局和文本视图的ID都相同或者是什么，如果是，则更改线性布局的ID。 通过下面的代码行，很明显您已经为线性布局和文本视图分配了相同的ID。
someLayout = (LinearLayout) findViewById(R.id.state2);
这里的问题是someLayout = (LinearLayout) findViewById(R.id.state2);
您正在尝试将textview转换为linearlayout。
使用yourtextview = (TextView) findViewById(R.id.state2);
改成
public void runNextTask(View v){ // method signature is worng
此外，如果textView位于activity_main.xml中。 无需夸大布局
setContentView(R.layout.activity_main); // is enough
并在onCreate中初始化textView
TextView modelTextview = (TextView)findViewById(R.id.state2);
如果您想以逐步删除的方式单击侦听器
android:onClick="runNextTask"
您正在尝试将textview转换为linearlayout。
