EditText编辑框

Question

我想为用户提供制作文字样式的选项 这个图像在edittext中（粗体斜体和普通的选项）。第一个用户选择文本然后单击按钮更改EditText中写入的文本的textStyle。 ：

这是代码

public class Addnew extends Activity {
Spinner spinner;
String select=null;
private String selec(String selected){
    return selected;

}

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.addnew);
    spinner = (Spinner) findViewById(R.id.comptypeinput);
    ArrayAdapter<CharSequence> spin= ArrayAdapter.createFromResource(Addnew.this,R.array.spinner,android.R.layout.simple_spinner_item);
    spin.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
    spinner.setAdapter(spin);

    spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        String selected = null;
        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            selected = arg0.getItemAtPosition(arg2).toString();
            select = selec(selected);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            Toast.makeText(Addnew.this, "Please Select Complaint Type", Toast.LENGTH_LONG).show();
        }
    });


    Button submit = (Button) findViewById(R.id.insert);
    submit.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {

            EditText comptimee= (EditText) findViewById(R.id.timeinput);
            EditText compaddresse= (EditText) findViewById(R.id.addressinput);
            EditText compdesce = (EditText) findViewById(R.id.descriptioninput);
            String username= getIntent().getStringExtra("user");
            String comptime = comptimee.getText().toString();
            String compaddress = compaddresse.getText().toString();
            String compdesc = compdesce.getText().toString();
            AddnewAsync as=new AddnewAsync();
            as.execute(select,comptime,compdesc,compaddress,username);
        }
    });
}

private class AddnewAsync extends AsyncTask<String, Void, String>{
    private Dialog pd ;
    @Override
    protected String doInBackground(String... params) {
        List<NameValuePair> nvp = new ArrayList<NameValuePair>();
        nvp.add(new BasicNameValuePair("comp_type", params[0]));
        nvp.add(new BasicNameValuePair("availtime", params[1]));
        nvp.add(new BasicNameValuePair("description", params[2]));
        nvp.add(new BasicNameValuePair("address", params[3]));
        nvp.add(new BasicNameValuePair("username", params[4]));
        HttpClient hc = new DefaultHttpClient();
        HttpPost hp = new HttpPost("http://172.31.144.231/test/andcompinsert.php");
        StringBuilder sb = new StringBuilder();
        String result=null;
        try {
            hp.setEntity(new UrlEncodedFormEntity(nvp));
            HttpResponse response = hc.execute(hp);
            HttpEntity ent= response.getEntity();
            InputStream is = ent.getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(is));
            String line = null;
            while((line=reader.readLine())!= null){
                sb.append(line+"\n");
            }
             result = sb.toString();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return result;
    }
    @Override
    protected void onPreExecute() {
        pd = ProgressDialog.show(Addnew.this, "Please Wait", "Uploading");
        super.onPreExecute();
    }
    @Override
    protected void onPostExecute(String result) {
        pd.dismiss();
        String s = result.trim();
        if(s.equals("success")){
            Toast.makeText(Addnew.this, "Updated Successfully", Toast.LENGTH_LONG).show();
            Intent inten = new Intent(Addnew.this,PreviousComp.class);
            String username= getIntent().getStringExtra("user");
            inten.putExtra("user", username);
            startActivity(inten);
        }else{
            Toast.makeText(Addnew.this, "Error Updating... Please Try Again...", Toast.LENGTH_LONG).show();
        }
        super.onPostExecute(result);
    }
}
}

在我的edittext compdesce中，我想要那些选项。

Answer 1

使用html标签（如final TextView txView=(TextView)findViewById(R.id.textView); final EditText txtEdit=(EditText)findViewById(R.id.edit); Button bt=(Button)findViewById(R.id.btn); bt.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String str=txtEdit.getText().toString(); txView.setText(Html.fromHtml(str)); } }); } 等）来设置在edittext中输入的文本文本并设置TextView的文本：

<b>

如果您输入的文字类似于＆＃34;则为</b>粗体文字gopkg.in/mgo.v2＆＃34;在您的editText结果中将是： ＆＃34;它是粗体文字＆＃34;
