【问题描述】：

我正在尝试打开一个 figure603.png 图像，该图像已在 res/drawable-hdpi、res/drawable-ldpi、res/drawable-mdpi 和 res/drawable-xhdpi 内分别拖放到 Eclipse 中

这是我的程序，

package com.rufflez.swipeytabs;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.view.View.OnClickListener;

import com.actionbarsherlock.app.SherlockFragment;

public class Fragment_6 extends SherlockFragment{

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){

    View v =inflater.inflate(R.layout.fragment_6, container, false); // inflate the layout
    TextView tv = (TextView) v.findViewById(R.id.textView1); // initialize textview using inflated view object 

    tv.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {           
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setData(Uri.parse("android.resource://com.rufflez.swipeytabs/" +  R.drawable.figure603));
    startActivity(intent);
    }
    }); 
    return v;
}

}

这是我的日志

当我单击文本时，假设打开了 figure603.png，但它却给了我一个关闭的力。可能是什么问题？

【解决方案1】：

你使用了错误的 URI

 Uri uri=Uri.parse("android.resource://your.package.here/drawable/image_name");

即

 intent.setData(Uri.parse("android.resource://your.package.here/drawable/image_name");

【讨论】：

我尝试将其切换到 intent.setData(Uri.parse("android.resource://com.rufflez.swipeytabs/drawable/figure603"));但它仍然是强制关闭的
@Catherine 为什么不使用 imageview 并将图像设置为 imageview
@Raghunandan 你指的是这个吗？ stackoverflow.com/questions/12619416/… 当我点击文本时，我试图打开一张图片。我可以在这种情况下使用 imageview 吗？
@Raghunandan public void onClick(View v) { ImageView iv= (ImageView)findViewById(R.id.img_selected_image); public static int getDrawable(Context context, String name)//获取id的方法 { Assert.assertNotNull(context); Assert.assertNotNull(name); return context.getResources().getIdentifier(name, //return id "figure603", context.getPackageName()); } image.setImageResource(Id);//使用这个方法设置id } });返回 v; }

【解决方案2】：

你应该使用这个代码：

intent.setData(Uri.parse("android.resource://com.rufflez.swipeytabs/drawable/figure603"));

代替：

intent.setData(Uri.parse("android.resource://com.rufflez.swipeytabs/" +  R.drawable.figure603));

我不确定，但您不需要 setData 的输入流吗？如果你这样做，将是这样做的代码：

InputStream stream = getContentResolver().openInputStream(uri);
