2020-05-20 ListView的Item中含有Butto
场景：ListView的Item中包含Button控件，会出现Item点击失效，不响应，Button可点击，响应。
解决方法：在Button的xml属性中加入这两句代码解决，
android:focusable="false"
android:focusableInTouchMode="false"
实现：Item可点击，响应，Button可点击，响应
代码：

package www.yalong.com.listview_button;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Adapter;
import android.widget.AdapterView;

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener{
ListView listView;
List list;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView=findViewById(R.id.listView);
list=new ArrayList();
for (int i=0;i<10;i++){
list.add("第"+i+"行数据");
}
MyAdapter adapter=new MyAdapter(MainActivity.this,list);
listView.setAdapter(adapter);
listView.setOnItemClickListener(this);
}
@Override
public void onItemClick(AdapterView adapterView, View view, int i, long l) {
Toast.makeText(MainActivity.this,"点击了第"+i+"行",Toast.LENGTH_LONG).show();
}
