Question

我希望将imageview视图用于新活动。我的imageview使用xmlparser。但如果我点击imageview，我的应用程序就会关闭。

这是我的代码：

   thumb_image.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View v)
            {
                 String title = ((TextView) findViewById(R.id.textURL)).getText().toString();
                 String date = ((TextView) findViewById(R.id.dateURL)).getText().toString();
                 String body = ((TextView) findViewById(R.id.bodyURL)).getText().toString();
                 ImageView thumb_image=(ImageView)findViewById(R.id.ImageURL); // thumb image
                 thumb_image.buildDrawingCache();
                 Bitmap image= thumb_image.getDrawingCache();
                  Bundle extras = new Bundle();
                 extras.putParcelable(KEY_IMAGEURL, image);
                 // Starting new intent
                 Intent i = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
                 i.putExtra(KEY_HEADLINE, title);
                 i.putExtra(KEY_ARTICLEDATE, date);
                 i.putExtra(KEY_BODY,body);
                 i.putExtras(extras);

                 startActivity(i);

我的单一活动代码

   Intent in = getIntent();
Bundle bun = in.getExtras();

 //Get XML values from previous intent
String headline = bun.getString(KEY_HEADLINE);
String date = bun.getString(KEY_ARTICLEDATE);
String Body = bun.getString(KEY_BODY);
//String image = bun.getString(KEY_IMAGEURL);
Bitmap image = (Bitmap) bun.getParcelable(KEY_IMAGEURL);
  WebView browser = (WebView)findViewById(R.id.webView1);

String HTML = ......................;
browser.loadData(HTML, "text/html", "utf-8");

这是我的应用程序的logcat

Answer 1

避免使用此buildDrawingCache（）方法根据android开发者文档

Build Drawing Cache

调用此方法会增加内存使用量并导致视图在软件中呈现一次，从而对性能产生负面影响。尝试另一种方法将图像网址或图像数据传递到另一个活动

试试这个..

像这样改变您的位图编码..

BitmapDrawable bitmapDrawable = ((BitmapDrawable) thumb_image.getDrawable());
Bitmap bitmap1 = bitmapDrawable .getBitmap();

示例

thumb_image.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { String title = ((TextView) findViewById(R.id.textURL)).getText().toString(); String date = ((TextView) findViewById(R.id.dateURL)).getText().toString(); String body = ((TextView) findViewById(R.id.bodyURL)).getText().toString(); BitmapDrawable bitmapDrawable = ((BitmapDrawable) thumb_image.getDrawable()); Bitmap image = bitmapDrawable.getBitmap(); Bundle extras = new Bundle(); extras.putParcelable(KEY_IMAGEURL, image); // Starting new intent Intent i = new Intent(this, SingleMenuItemActivity.class); i.putExtra(KEY_HEADLINE, title); i.putExtra(KEY_ARTICLEDATE, date); i.putExtra(KEY_BODY,body); i.putExtras(extras); startActivity(i); } });

我想要意图imageview
