【问题描述】：
我尝试解决它已经好几天了 我试过这个例子： http://www.mkyong.com/android/android-gridview-example/
我想在 customadapter 的搜索栏上检测 onStopTrackingTouch。 这个例子与 OnItemClickListener 一起工作得很好，但是如果我在布局 mobile.xml 中添加一个搜索栏，我无法检测到 StopTrackingTouch 并获取搜索栏值！该死的怎么解决？
布局：mobile.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp" >
<ImageView
android:id="@+id/grid_item_image"
android:layout_width="50px"
android:layout_height="50px"
android:layout_marginRight="10px"
android:src="@drawable/android_logo" >
</ImageView>
<TextView
android:id="@+id/grid_item_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/label"
android:layout_marginTop="5px"
android:textSize="15px" >
</TextView>
<SeekBar
android:layout_width="267dp"
android:layout_height="wrap_content"
android:id="@+id/seekBar2"
android:focusable="false"/>
</LinearLayout>
适配器：
package com.mkyong.android.adapter;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import com.mkyong.android.R;
public class ImageAdapter extends BaseAdapter {
private Context context;
private final String[] mobileValues;
public ImageAdapter(Context context, String[] mobileValues) {
this.context = context;
this.mobileValues = mobileValues;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if (convertView == null) {
gridView = new View(context);
// get layout from mobile.xml
gridView = inflater.inflate(R.layout.mobile, null);
// set value into textview
TextView textView = (TextView) gridView.findViewById(R.id.grid_item_label);
textView.setText(mobileValues[position]);
// set image based on selected text
ImageView imageView = (ImageView) gridView.findViewById(R.id.grid_item_image);
String mobile = mobileValues[position];
if (mobile.equals("Windows")) {
imageView.setImageResource(R.drawable.windows_logo);
} else if (mobile.equals("iOS")) {
imageView.setImageResource(R.drawable.ios_logo);
} else if (mobile.equals("Blackberry")) {
imageView.setImageResource(R.drawable.blackberry_logo);
} else {
imageView.setImageResource(R.drawable.android_logo);
}
} else {
gridView = (View) convertView;
}
return gridView;
}
@Override
public int getCount() {
return mobileValues.length;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
}
活动：
package com.mkyong.android;
import com.mkyong.android.adapter.ImageAdapter;
import android.app.Activity;
import android.os.Bundle;
import android.widget.AdapterView;
import android.widget.GridView;
import android.widget.TextView;
import android.widget.Toast;
import android.view.View;
import android.widget.AdapterView.OnItemClickListener;
public class GridViewActivity extends Activity {
GridView gridView;
static final String[] MOBILE_OS = new String[] { "Android", "iOS","Windows", "Blackberry" };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
gridView = (GridView) findViewById(R.id.gridView1);
gridView.setAdapter(new ImageAdapter(this, MOBILE_OS));
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
position=position;
int a=3;
// Toast.makeText(getApplicationContext(),((TextView) v.findViewById(R.id.grid_item_label)).getText(), Toast.LENGTH_SHORT).show();
// Toast.makeText(getApplicationContext(),((TextView) v.findViewById(R.id.From)).getText(), Toast.LENGTH_SHORT).show();
}
});
}
}
我尝试添加这个但不工作（当然）：
gridView.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
如何解决这个问题？
【问题讨论】：
-
onProgressChanged也不起作用吗？ -
您的 girdview onitemclick 会覆盖行项目视图 onclick，从 gridview 中清除 itemclick 或处理 gridview itemclick 下的点击。
-
好的，使用 [SeekBar in a ListActivity using an ArrayAdapter][1] [1] 中的指南：stackoverflow.com/questions/6211339/…
