我有一个获取数字的edittext字段。当字段清除时，我可以随意触摸它。如果出现一个字符，我关闭键盘，第二次点击edittext，应用程序将获得一个get运行时。
我试图找到一些方法或任何东西来帮助我在Android文档有关EditText，但我没有找到它。
这是我的代码
java

package com.example.aplikacja_testowa;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class CallSettings extends AppCompatActivity {
    private TextView textView;
    private EditText editText;
    private Button saveButton;

    public static final String SHARED_PREFS = "sharedPrefs";
    public static final String TEXT = "text";
    //public static final

    private String text;

    ////////////////
    int dem=0;
    int them;
    int selectTheme = 2;
    ////////////////

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        them=SmsSettings.loadData(CallSettings.this, "style.txt", null, dem);
        selectTheme = them;
        Log.i("TAG", "onCreate selectTheme: "+selectTheme);
        FontSettings.setDynamicTheme(CallSettings.this, selectTheme);

        setContentView(R.layout.activity_call_settings);
        textView = findViewById(R.id.callInstruction);
        editText = findViewById(R.id.textPhoneNumber);
        saveButton = findViewById(R.id.save_button);
    }

    public void savePhoneNumber(View v){
        SmsSettings.saveData(this, "callnumber.txt", editText, 0);
        Toast.makeText(this, R.string.number_saved, Toast.LENGTH_SHORT).show();
    }
}

显然，无论FontSettings.setDynamicTheme()改变了什么主题细节，它最终都会让你的小部件处于无效或不完整的状态，或者样式引用了不存在的资源。
我的猜测是，如果EditText中没有输入内容，它为什么会起作用，因为如果没有内容，小部件就不需要绘制它的一些元素。所以你可以让你的空EditText多次聚焦，不会发生什么不好的事情，但是如果有任何内容和样式，即引用缺少的资源。我猜FontSettings是外部项目，所以我会检查更新的拳头，然后我会检查它试图应用的样式。
