int[] etColorId = new int[] {R.id.etColor1, R.id.etColor2, R.id.etColor3, R.id.etColor4, R.id.etColor5,
            R.id.etColor6, R.id.etColor7, R.id.etColor8, R.id.etColor9, R.id.etColor10, R.id.etColor11,
            R.id.etColor12, R.id.etColor13, R.id.etColor14, R.id.etColor15};

    for (int editText : etColorId) {
        findViewById(editText).setOnFocusChangeListener(new OnFocusChangeListener() {

            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                // TODO Auto-generated method stub
                v.setEnabled(false);
            }
        });

    int[] btnEditId = new int[] {R.id.btnEdit1, R.id.btnEdit2, R.id.btnEdit3, R.id.btnEdit4, R.id.btnEdit5,

    for (int button : btnEditId) {
        findViewById(button).setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                v.setEnabled(true);

你好！我想问一下如何在点击按钮时将焦点集中到EditText上。场景是我有一堆EditTexts和Buttons。每个按钮对应一个特定的EditText。我想要的是，例如，如果我点击button1，EditText1将被聚焦。然后当我单击其他按钮时，EditText对应于该按钮将被聚焦，然后其他EditTexts将被禁用。

Answer 1

OnFocusChangeListener的代码必须稍加修改，对于您需要最终引用您想要修改的任何对象的匿名类，因为您要修改EditText

final int[] etColorId = new int[] {R.id.etColor1, R.id.etColor2, R.id.etColor3, R.id.etColor4, R.id.etColor5,
            R.id.etColor6, R.id.etColor7, R.id.etColor8, R.id.etColor9, R.id.etColor10, R.id.etColor11,
            R.id.etColor12, R.id.etColor13, R.id.etColor14, R.id.etColor15};

现在为OnClickListener做这样的

for (int i=0;i<btnEditId.length;i++) 
{
    final int counter=i;
    int button=btnEditId[i];
    findViewById(button).setOnClickListener(new OnClickListener() 
    {

        @Override
        public void onClick(View v) 
        {

            // HERE v refers to button itself on which you clicked, 
            // you need to update get edit text so
            // based on ith position accessing the same edit as the button correspond too
            EditText edt=etColorId[counter];
            edt.setEnabled(true);
            edt.requestFocus();
            // and you are DONE!!!
        }
    });
}

<强>更新

 new OnFocusChangeListener() 
 {

            @Override
            public void onFocusChange(View v, boolean hasFocus) 
            {

                if(!hasFocus) 
                { // lost focus
                       v.setEnabled(false);
                }
                else
                {
                    //you are already enabling on button click
                }
            }
  });

Answer 2

内部

onClick()
{
    edittext.setFocusableInTouchMode(true);
    edittext.requestFocus();
}

Answer 3

每次失去焦点并获得焦点时，都会调用onFocusChange。

@Override
public void onFocusChange(View v, boolean hasFocus) {
    // TODO Auto-generated method stub
    v.setEnabled(false);
}

所以，首先你需要改变代码

@Override
public void onFocusChange(View v, boolean hasFocus) {
    // TODO Auto-generated method stub
    if(hasFocus) {// gain focus
       // Code block
    }
    if(!hasFocus) { // lost focus
        // Code block
    }
}

每次按EditText

时，您Button都会被停用

单击按钮 - Android后，将焦点设置为EditText
