Question

在我的应用程序中，我将从图库中选择图像并将其放入编辑文本，用户可以将图像放在编辑文本字段中，如果有任何想法，用户也可以在编辑文本字段中键入任何内容救命。

Emoticon.java

public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

         setContentView(R.layout.emoticon);
         Pick = (Button)findViewById(R.id.pick);
         EditText text = (EditText) findViewById(R.id.editText);
         Pick.setOnClickListener(new OnClickListener() {
         public void onClick(View v) 
                {
                    Intent intent = new Intent();
                    // Picture from camera
                    intent.setType("image/*");
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                   startActivityForResult(intent, 10);

                }
            });
    }
    public void onActivityResult(int requestCode, int resultCode, Intent data){
                if (requestCode == requestCode) {
                    // return from file upload
                    if (requestCode == 10 && resultCode == Activity.RESULT_OK) {

                        Uri selectedImage = data.getData();

                        String[] filePathColumn = {MediaStore.Images.Media.DATA};
                        Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
                        cursor.moveToFirst();
                        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                        String filePath = cursor.getString(columnIndex);
                        cursor.close();
                        SpannableString ss = new SpannableString("abc");
                        Drawable d = img.getDrawable();
                        d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
                        ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE);
                        ss.setSpan(span, 0, 3, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
                        EditText.setText(ss);      

                    }
                    }
         }

ImageGetter imageGetter = new ImageGetter() {
            public Drawable getDrawable(String filePath) {
                Drawable d = Drawable.createFromPath(filePath);
                d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
                return d;
            }
        };

        cs = Html.fromHtml(
                "<img src='"
                        + filePath
                        + "'/>", imageGetter, null);
        edttxtemoji.setText(cs);

你可以试试上面的代码。 filePath是用户选择的文件的路径。
