Question

我在以下段落中添加了我的布局：

布局：

<EditText
        android:id="@+id/EditTextEmissionDetails"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:gravity="top"
        android:hint="Emission Details"
        android:scrollbarStyle="insideOverlay"
        android:isScrollContainer="true">
    </EditText>

在本段中，我想通过检查第一个（＆＃34; 0＆＃34;）和第二个（x，b，d）字符来显示输入是文本还是十六进制，二进制，十进制，以及然后在新添加的布局部分显示结果。

爪哇：

import android.os.Bundle;
import android.view.KeyEvent;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.TextView.OnEditorActionListener;

import java.io.IOException;

public class ConsoleActivity extends SerialPortActivity {
    String dataformat;
    EditText mReception;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.console);

        mReception = (EditText) findViewById(R.id.EditTextReception);

        EditText Emission;
        Emission = (EditText) findViewById(R.id.EditTextEmission);
        EditText EmissionDetails;
        EmissionDetails = (EditText) findViewById(R.id.EditTextEmissionDetails);

        Emission.setOnEditorActionListener(new OnEditorActionListener() {

            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                int i;
                CharSequence t = v.getText();
                char[] text = new char[t.length()];
                for (i=0; i<t.length(); i++) {
                    text[i] = t.charAt(i);
                    dataformat = "text";
                    if (text[0] == '0') {
                        System.out.println("I got a Zero");
                        if (text[1] == 'b') {
                            dataformat = "binary";
                        }
                        if (text[1] == 'd') {
                            dataformat = "decimal";
                        }
                        if (text[1] == 'x') {
                            dataformat = "hex";
                        }
                    }
                    EmissionDetails = "Dataformat " + text[0] + text[1] + " is " + dataformat;
                }
                try {
                    mOutputStream.write(new String(text).getBytes());
                    mOutputStream.write('\n');
                } catch (IOException e) {
                    e.printStackTrace();
                }
                return false;
            }
        });
    }

无论我尝试什么，正如Android-Studio中的红灯所示，迟早会回到开头。

如果输入十六进制数据，我应该尝试调整以仅显示句子（以＆＃34; 0x＆＃34;开头）：＆＃34;数据格式0x为十六进制＆＃34;

Answer 1

     EmissionDetails.setSingleLine(true) by programatically

    or

    do by xml
<EditText
        android:id="@+id/EditTextEmissionDetails"
    android:singleline="true"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:gravity="top"
        android:hint="Emission Details"
        android:scrollbarStyle="insideOverlay"
        android:isScrollContainer="true">
    </EditText>
