我有一个带有一些文本的imageView，我想通过onClick按钮保存到我的SD卡中。这就是我实现它的方式：
ImageView blankcard= (ImageView) findViewById(R.id.blankcard);
blankcard.setBackgroundResource(R.drawable.temp3);
btn3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Display the message in textview
TextView stv1 = (TextView) findViewById(R.id.crdName);
TextView stv2 = (TextView) findViewById(R.id.crdCompany);
TextView stv3 = (TextView) findViewById(R.id.crdPhone);
TextView stv4 = (TextView) findViewById(R.id.crdMobile);
TextView stv5 = (TextView) findViewById(R.id.crdAddress);
TextView stv6 = (TextView) findViewById(R.id.crdWebsite);
TextView stv7 = (TextView) findViewById(R.id.crdEmail);
TextView stv8 = (TextView) findViewById(R.id.crdTitle);
Intent intent=getIntent();
String Name = intent.getStringExtra("name");
String Company = intent.getStringExtra("company");
String Phone = intent.getStringExtra("phone");
String Mobile = intent.getStringExtra("mobile");
String Address = intent.getStringExtra("address");
String Email = intent.getStringExtra("email");
String Website = intent.getStringExtra("website");
String Title = intent.getStringExtra("title");
stv1.setText(Name+" ");
stv2.setText(Company);
stv3.setText(" "+Phone);
stv4.setText(Mobile+" ");
stv5.setText(" "+Address);
stv6.setText(" "+Email);
stv7.setText(Website+" ");
stv8.setText(Title+" ");
stv1.setVisibility(View.VISIBLE);
stv2.setVisibility(View.VISIBLE);
stv3.setVisibility(View.VISIBLE);
stv4.setVisibility(View.VISIBLE);
stv5.setVisibility(View.VISIBLE);
stv6.setVisibility(View.VISIBLE);
stv7.setVisibility(View.VISIBLE);
stv8.setVisibility(View.VISIBLE);
blankcard.setBackgroundResource(R.drawable.temp3);
blankcard.setDrawingCacheEnabled(true);
Bitmap bitmap = blankcard.getDrawingCache();
String root = Environment.getExternalStorageDirectory().toString();
File newDir = new File(root + "/MapCards");
newDir.mkdirs();
Random gen = new Random();
int n = 10000;
n = gen.nextInt(n);
String fotoname = "Photo-"+ n +".jpg";
File file = new File (newDir, fotoname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
Toast.makeText(getApplicationContext(), "Saved to your folder", Toast.LENGTH_SHORT ).show();
} catch (Exception e) {
}
}
});
单击按钮后，将在某个目录中创建文件并保存图像视图。但我只能看到模板，而不是我已经在imageView上设置的文本。如何更有效地使用Drawable来实现这一目标？谢谢。
