如何滑动 1-2 列表视图右侧 2-3 列表视图右侧以及 1-2 左侧 2-3 左侧
我是 android 新手，我想向右滑动 1-2 列表视图 2-3 右侧列表视图以及 1-2 左侧 2-3 左侧，
我怎样才能做到这一点？
提前致谢。
这是我的代码
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.inspire);
Context contex;
activity = this;
rowItems = fetchTwitterPublicTimeline();
rowItems1 = fetchTwitterPublicTimeline1();
rowItems2 = fetchTwitterPublicTimeline2();

btn2 = (Button) findViewById(R.id.button2);
btn3 = (Button) findViewById(R.id.button3);

ImageView imageView = (ImageView) findViewById(R.id.icon);
final ListView listView = (ListView) findViewById(R.id.listview);
adapter = new InspireAdapter(this, R.layout.row, rowItems);
listView.setAdapter(adapter);
OnItemClickListener listener = new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
final int position, long id) {
}
};
listView.setOnItemClickListener(listener);
final ListView listView1 = (ListView) findViewById(R.id.listview1);
adapter1 = new InspireAdapter1(this, R.layout.row1, rowItems1);
// listView1.setAdapter(adapter1);
OnItemClickListener listener1 = new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
};
listView1.setOnItemClickListener(listener1);
final ListView listView2 = (ListView) findViewById(R.id.listview2);
adapter2 = new InspireAdapter2(this, R.layout.row2, rowItems2);
// listView2.setAdapter(adapter2);
OnItemClickListener listener2 = new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
};
listView2.setOnItemClickListener(listener2);

【问题讨论】：
-
一切皆有可能......但Android有自己的设计模式......你应该遵循它们。
-
我在列表视图中实现了投掷手势我完成了向右滑动 1-2 列表视图但仍然没有滑动 2-3 向右滑动列表视图
-
@PankajKumar 我认为 android 在其设计模式中也包含滑动屏幕。所以要冷静它不是开箱即用的要求。 Android 支持并提供一种通过滑动创建屏幕的方法
-
@Sameer 我的评论是针对附加屏幕的...我没有说滑动不在 Android 中。我说的对吗？
