我已经在我的mainactivity中为我的textview添加了onClick并且我没有错误但是当我运行应用程序时崩溃说应用程序已停止工作，即使我的代码中没有错误我也不知道问题是什么
我希望你能帮助我，并提前致谢
这是我的logcat

并且是我的mainactivity.java
package imamalsajadsayings.android.com;
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.view.View.OnClickListener;
public class MainActivity extends Activity {
private LayoutInflater inflater;
private LinearLayout someLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView someLayout = (TextView)findViewById(R.id.state2);
inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
runNextTask(someLayout);
}
public void runNextTask(View v){
LinearLayout mInflatedLayout = (LinearLayout) inflater.inflate(R.layout.activity_main, null);
@SuppressWarnings("unused")
final TrackerInfo newInfo = new TrackerInfo();
//set up for model selection
someLayout.addView(mInflatedLayout);
someLayout = (LinearLayout) findViewById(R.id.linearlayout1); //layout present in
someLayout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
这是我对textviews和linearlayout的主要活动

答案 0 :(得分：0)
这真的很有趣：
E/AndroidRuntime(1559): Caused by: java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.LinearLayout
private LinearLayout someLayout;
和另一个困惑的命名
TextView someLayout = (TextView)findViewById(R.id.state2);
并且，如果someLayout在从布局加载之前可以addView()，那怎么可能呢？
someLayout.addView(mInflatedLayout);
someLayout = (LinearLayout) findViewById(R.id.linearlayout1);
好吧，我建议你先从正确的基础Android学习开始，
private LayoutInflater inflater;
private LinearLayout someLayout;
private TextView mTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTextView = (TextView) findViewById( R.id.state2 );
mTextView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// do something here
}
});
}
答案 1 :(得分：0)
