編程創建並將texttext對齊到文本視圖的右邊

Question

我已經構建了一個android應用程序，當用戶按下按鈕時，該應用程序會在UI上創建一個textview和一個edittext。目前，當你按'添加'按鈕時，創建了兩個字段，但編輯文本出現在textview下面，我希望edittext出現在屏幕上，並與textview的右側對齊，如下所示：

[addbutton]

[TextView的] [的EditText]
[TextView的] [的EditText]
[TextView的] [的EditText]

代碼：

private OnClickListener addForm() { 

     return new OnClickListener() { 

      @Override 
      public void onClick(View v) { 

       mLayout.addView(createNewTextView(numberString)); 
       mLayout.addView(createNewEditText(null)); 
       numberInt = Integer.parseInt(numberString); 
       numberInt++; 
       numberString = Integer.toString(numberInt); 
      } 
     }; 
    } 
    // add textview 
    private TextView createNewTextView(String text) { 
     final TextView textView = new TextView(this); 
     textView.setLayoutParams(lparams); 
     textView.setText(text); 
     return textView; 
    } 

    // add edittext 
    private EditText createNewEditText(String text) { 
     final EditText editText = new EditText(this); 

     editText.setLayoutParams(lparams); 
     editText.setText(text); 
     return editText; 
    }

行，所以我改了一下週圍的代碼我認爲應該工作，但EditText上仍出現以下任何人都可以看到我要去哪裏錯了或改變我的代碼，使其工作？感謝

新代碼：

private OnClickListener add() { 

     return new OnClickListener() { 

      @Override 
      public void onClick(View v) { 

       createNewTextView(numberString); 

       numberInt = Integer.parseInt(numberString); 
       numberInt++; 
       numberString = Integer.toString(numberInt); 



      } 
     }; 
    } 






    // add textview 
    private void createNewTextView(String text) { 


     final TextView textView = new TextView(this); 

     textView.setLayoutParams(lparams); 
     textView.setText(text); 
     textView.setId(numberInt); 

     mLayout.addView(textView); 

     createNewEditText(textView); 

    } 

    // add edittext 
    private void createNewEditText(TextView textView) { 




     final EditText editText = new EditText(this); 


     lparams.addRule(RelativeLayout.RIGHT_OF, textView.getId()); 
     editText.setLayoutParams(lparams); 
     mLayout.addView(editText); 

    }

所有Java和XML以下代碼：

的Java：

import android.app.ActionBar.LayoutParams; 
import android.app.Activity; 
import android.os.Bundle; 
import android.view.Gravity; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.LinearLayout; 
import android.widget.TextView; 
import android.widget.Toast; 

public class MainActivity extends Activity { 
private LinearLayout mLayout; 
private Button mButton; 
private String numberString = "1"; 
private int numberInt = 1; 
final LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT,  LayoutParams.WRAP_CONTENT); 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     mLayout = (LinearLayout) findViewById(R.id.linearLayout); 
     mButton = (Button) findViewById(R.id.button); 
     mButton.setOnClickListener(add()); 
     TextView textView = new TextView(this); 
     textView.setText("New text"); 
    } 

    private OnClickListener add() { 

     return new OnClickListener() { 

      @Override 
      public void onClick(View v) { 

       mLayout.addView(createNewTextView(numberString)); 
       mLayout.addView(createNewEditText(null)); 
       numberInt = Integer.parseInt(numberString); 
       numberInt++; 
       numberString = Integer.toString(numberInt); 



      } 
     }; 
    } 

// add textview 
    private TextView createNewTextView(String text) { 


     final TextView textView = new TextView(this); 

     textView.setLayoutParams(lparams); 
     textView.setText(text); 
     return textView; 

    } 

    // add edittext 
    private EditText createNewEditText(String text) { 

    final EditText editText = new EditText(this); 

     editText.setLayoutParams(lparams); 
     editText.setText(text); 
     editText.setId(numberInt); 

     int i = editText.getId(); 

     Toast toast= Toast.makeText(MainActivity.this,"edittext ID:" + i ,  Toast.LENGTH_SHORT); 
     toast.setGravity(Gravity.CENTER, 0, -100); 
     toast.show(); 

     return editText; 

    } 
} 

XML：

<Button 
    android:id="@+id/button" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Add+" 
/> 

Answer 1

使用RelativLayout並設置規則像android:layout_toRightOf="@+id/textview"

Answer 2

使用相對佈局作爲容器和使用相對佈局PARAMS對齊的EditText和TextView的。在相對佈局參數中有alignright，alignleft等。就像在xml中一樣。 developer.android.com/reference/android/widget/RelativeLayout.LayoutParams.html

Answer 3

集ID爲TextView和EditText然後用RelativeLayoutLayoutParams到右對齊或使用像params.addRule（RelativeLayout.ALIGN_LEFT，編號規則左）;

如果你的主要佈局是LinearLayout然後確保你的主要佈局方向是水平的...，並使用下面的代碼

LayoutParams lparams= new RelativeLayout.LayoutParams(new ViewGroup.MarginLayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT)); 

     TextView textView = new TextView(this); 

     textView.setLayoutParams(lparams); 
     textView.setText("TextView"); 
     textView.setId(1); 

     mLayout.addView(textView); 

     EditText editText = new EditText(this); 
     lparams.addRule(RelativeLayout.ALIGN_RIGHT, textView.getId()); 
     editText.setLayoutParams(lparams); 
     mLayout.addView(editText);
