Question

我正在尝试打开一个figure603.png图像，我已经在res / drawable-hdpi，res / drawable-ldpi，res / drawable-mdpi和res / drawable-xhdpi

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logcat

当我点击文字时，假设打开figure603.png，但它会给我一个力量关闭。可能是什么问题？

Answer 1

您使用的是错误的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");

Answer 2

您应该使用以下代码：

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

而不是：

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

我不确定这一点，但是你不需要setData的输入流吗？如果你这样做将是代码：

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

如何打开保存在drawable中的图像？
