将焦点更改为 EditText Android [英] Change Focus to EditText Android

问题描述

我的 Activity 上有 2 个 EditText，并将 maxLength 设置为 5.

I have 2 EditText's on my Activity and set the maxLength to 5.

现在我想将焦点设置到editText2，如果在editView1中达到5的长度...

Now I want to set the focus to editText2, if the length of 5 is reached in editView1...

我试过了:

editView1.setOnKeyListener(new OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if(editView1.getText().length() == 5)
            editView2.requestFocus();
        return false;
    }
});

但它不会工作..

推荐答案

这可行

final EditText editText1 = (EditText) findViewById(R.id.editText1);
final EditText editText2 = (EditText) findViewById(R.id.editText2);

editText1.setOnKeyListener(new OnKeyListener() {

    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if(editText1.getText().length() == 5)
            editText2.requestFocus();
        return false;
    }
});
