我正在显示来自数据库的事件名称并将它们添加到Layout。现在我想打开另一个布局，其中包含我点击的特定事件的详细信息。如何添加{{1我显示的文字？我想点击文字。

listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getApplicationContext(),
"Click ListItem Number " + position, Toast.LENGTH_LONG)
.show();
}
});

这很简单：
txtView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
希望它有所帮助。
答案 2 :(得分：1)
这很简单，就是那样：
TextView textView = (TextView) findViewById(R.id.yourtextview);
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Codes for action
}
});
<强>更新 Converting string into TextView?
TextView idText = new TextView(this);
idText.setText(row.get(0).toString());
tableRow.addView(idText);
TextView storeText = new TextView(this);
storeText.setText(row.get(1).toString());
tableRow.addView(storeText);
TextView maggiText = new TextView(this);
maggiText.setText(row.get(2).toString());
tableRow.addView(maggiText);
答案 3 :(得分：0)
将 onclickListener 设置为TextView。
就像这样： -
TextView = textView (TextView) findViewById(R.id.TEXTVIEW_ID);
textview.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
答案 4 :(得分：0)
您可以像这样将ArrayList设置为ListView。
private ListView lv;
on onCreate方法
lv = (ListView) findViewById(R.id.listView1);
像这样更改此行listItems.add(all.get(0)+" \n venue:"+all.get(1)+" Price:"+all.get(3));。
listItems.add("ID"+all.get(0));
listItems.add("Venue"+all.get(1));
......................... etc
然后添加到addapter
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
listItems );
lv.setAdapter(arrayAdapter);
之后你可以set OnItemClickListner喜欢这个
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int position, long id) {
// Put your custom code here
}
});
将此添加到activity_full_details.xml
<ListView
android:id="@+id/listView1"
android:layout_width="288dp"
android:layout_height="330dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="62dp" >
</ListView>
