我对使用从主机应用程序到智能扩展的意图有疑问。我在 hostapp 中有 Class ActivityReceiver
package com.PrinterStatus.AppLab;
import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import com.sonyericsson.extras.liveware.extension.controlsample.*;
public class ActivityToSmartWatch extends Activity {
private Activity activity;
private ArrayList<String[]> data;
private static LayoutInflater inflater = null;
public String[] inkLevels = new String[5];
public final String EXTRA_MESSAGE = "com.PrinterStatus.AppLab.MESSAGE";
View message;
String [][] storePrintIMC= new String [4][4];
public static final String ARRAYS_COUNT = "com.PrinterStatus.AppLab.ARRAYS_COUNT";
public static final String ARRAY_INDEX = "com.PrinterStatus.AppLab.ARRAY_INDEX";
public ActivityToSmartWatch(Activity a, ArrayList<String[]> inkLevels) {
activity = a;
data = inkLevels;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void sendMessage(View view)
{
Bundle bundle = new Bundle();
final String data[][] = storePrintIMC;
int count = data.length;
bundle.putInt(ARRAYS_COUNT, count);
for (int i = 0; i < count; i++)
{
bundle.putStringArray(ARRAY_INDEX + i, data[i]);
}
Intent intent = new Intent(this, ActivityReceiver.class);
intent.putExtras(bundle);
startActivity(intent);
}
public int getCount() {
return data.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public String[] getPrintIMC (int position)
{
System.arraycopy(data.get(position), 0, inkLevels, 0, data.get(position).length);
data.get(position);
//sendMessage(message);
if (position == 0 )
{
storePrintIMC[0][0]=inkLevels[0];
storePrintIMC[0][1]=inkLevels[1];
storePrintIMC[0][2]=inkLevels[2];
storePrintIMC[0][3]=inkLevels[3];
}
if (position == 1 )
{
storePrintIMC[1][0]=inkLevels[0];
storePrintIMC[1][1]=inkLevels[1];
storePrintIMC[1][2]=inkLevels[2];
storePrintIMC[1][3]=inkLevels[3];
}
if (position == 2 )
{
storePrintIMC[2][0]=inkLevels[0];
storePrintIMC[2][1]=inkLevels[1];
storePrintIMC[2][2]=inkLevels[2];
storePrintIMC[2][3]=inkLevels[3];
}
if (position == 3 )
{
storePrintIMC[3][0]=inkLevels[0];
storePrintIMC[3][1]=inkLevels[1];
storePrintIMC[3][2]=inkLevels[2];
storePrintIMC[3][3]=inkLevels[3];
//sendMessage(message);
}
return inkLevels;
}
}
I want to send inkLevels to my smartextension(different package) so I using intent inside sendMessage method. And inside the smartextension, I have class activity receiver.
package com.sonyericsson.extras.liveware.extension.controlsample;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
public class ActivityReceiver extends Activity {
public ArrayList<String[]> arrays ;
public String[]color = new String [4];
public String[][] inkLev ;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle bundle = getIntent().getExtras();
if (bundle != null)
{
int count = bundle.getInt("com.PrinterStatus.AppLab.ARRAYS_COUNT", 0);
ArrayList<String[]> arrays = new ArrayList<String[]>(count);
for (int i = 0; i < count; i++)
{
arrays.add(bundle.getStringArray("com.PrinterStatus.AppLab.ARRAY_INDEX" + i));
String[][] inkLev = arrays.toArray(new String[][]{});
}
}
}
public String[] getInkLevel()
{
color[0]= inkLev[0][2];
color[1]= inkLev[1][2];
color[2]= inkLev[2][2];
color[3]= inkLev[3][2];
return color;
}
}
我想使用可变颜色来显示我将放在另一个类中的接口中的值。但是我的编码方式仍然有问题。为什么它仍然找不到类？我忘记了什么吗？
