在视图下方显示烤面包部件

本文介绍了在视图下方显示烤面包部件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 对于那些曾经帮助过我这个项目的人，非常感谢你！我的代码不再有任何问题，我做了额外的调整。现在应用程序现在实际上很强大，我想再做一件事。

查看布局在这里。

通常，烤面包视图出现在屏幕的底部中心。 OnClick被调用后，我想让它出现在下面（8dp）Submit按钮。如何实现这一点。

请参阅我的更新完成项目在这里。

package com.lookjohn.guessnumber; import java.util.Random; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast; public class MainActivity extends Activity {随机随机; 按钮按钮; EditText文字; int input; int MIN，MAX; int comp; int guesses; public void onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; setContentView（R.layout.activity_main）; random = new Random（）; button =（Button）findViewById（R.id.button1）; text =（EditText）findViewById（R.id.editText1）; MIN = 1; MAX = 100; comp = random.nextInt（MAX - MIN + 1）+ MIN; //生成1到100之间的随机数。 guesses = 0; button.setOnClickListener（myhandler1）; } View.OnClickListener myhandler1 = new View.OnClickListener（）{ public void onClick（View v）{ / /实现最大数量的猜测，检测 //数量的猜测并从方法返回。 String value = text.getText（）。toString（）; //从editTextView的输入获取值 //如果用户提交一个空的EditText，返回以防止崩溃。 if（value.isEmpty（））{ Toast.makeText（MainActivity.this，你必须输入一个猜测！，Toast.LENGTH_SHORT）; return; } input = Integer.parseInt（value）; //将字符串转换为整数 guesses ++; if（input> 100）{ Toast.makeText（MainActivity.this，该数字大于100. Not valid！， Toast.LENGTH_SHORT）。显示（）; return; } else if（input< comp） Toast.makeText（MainActivity.this，你的数字太小了， Toast.LENGTH_SHORT）.show（）; else if（input> comp） Toast.makeText（MainActivity.this，你的数字太大了， Toast.LENGTH_SHORT）.show（）; else Toast.makeText（MainActivity.this，好工作！答案是+ comp +.\\\+ 你做了+猜猜+ guesses.\\\+ 重新启动应用再试一次。， Toast.LENGTH_LONG）.show（）; } }; @Override public boolean onCreateOptionsMenu（菜单菜单）{ //扩充菜单;如果存在，则会将项目添加到操作栏。 getMenuInflater（）。inflate（R.menu.main，menu）; 返回true; } }

解决方案

从我学到的知识来看，这是我想到的最好的方案。如果（输入> 100）{ Toast（$）

toast = Toast.makeText（MainActivity.this， R.string.over_guess， Toast.LENGTH_SHORT）; toast.setGravity（Gravity.CENTER，0，0）; toast.show（）; return; } else if（input< comp）{ Toast toast = Toast.makeText（MainActivity.this， getString（R.string.guess_low，input）， Toast.LENGTH_SHORT）; toast.setGravity（Gravity.CENTER，0，0）; toast.show（）; } else if（input> comp）{ Toast toast = Toast.makeText（MainActivity.this， getString（R.string.guess_high，input）， Toast.LENGTH_SHORT）; toast.setGravity（Gravity.CENTER，0，0）; toast.show（）; } else { Toast toast = Toast.makeText（MainActivity.this， getString（R.string.correct，comp，guesses）， Toast.LENGTH_LONG ）; toast.setGravity（Gravity.CENTER，0，0）; toast.show（）; }

For those who helped me out earlier regarding this project, thank you very much! My code no longer has any problems, and I made extra tweaks. Now that the app is actually robust now, I want to do one more thing.

See screenshot of the layout here.

Normally, the toast view appears at the bottom center of the screen. I want to make it appear just below (8dp) the Submit button once OnClick is called. How can I accomplish this.

package com.lookjohn.guessnumber; import java.util.Random; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast; public class MainActivity extends Activity { Random random; Button button; EditText text; int input; int MIN, MAX; int comp; int guesses; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); random = new Random(); button = (Button)findViewById(R.id.button1); text = (EditText)findViewById(R.id.editText1); MIN = 1; MAX = 100; comp = random.nextInt(MAX - MIN + 1) + MIN; // Generate random number between 1 and 100. guesses = 0; button.setOnClickListener(myhandler1); } View.OnClickListener myhandler1 = new View.OnClickListener() { public void onClick(View v) { // Implemented max number of guesses, detect // number of guesses and return from the method. String value = text.getText().toString(); // Get value from input from editTextView // If user submits an empty EditText, return to prevent a crash. if (value.isEmpty()) { Toast.makeText(MainActivity.this, "You must enter a guess!", Toast.LENGTH_SHORT); return; } input = Integer.parseInt(value); // Turn string into integer guesses++; if (input > 100) { Toast.makeText(MainActivity.this, "That number is greater than 100. Not Valid!", Toast.LENGTH_SHORT).show(); return; } else if (input < comp) Toast.makeText(MainActivity.this, "Your number is too small.", Toast.LENGTH_SHORT).show(); else if (input > comp) Toast.makeText(MainActivity.this, "Your number is too big.", Toast.LENGTH_SHORT).show(); else Toast.makeText(MainActivity.this, "Good job! The answer was " + comp + ".\n" + "You made " + guesses + " guesses.\n" + "Restart the app to try again.", Toast.LENGTH_LONG).show(); } }; @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } }

解决方案

From what I learned, this is the best I came up with for the program. Doing this puts the Toast message in the center of the phone.

if(input > 100) { Toast toast = Toast.makeText(MainActivity.this, R.string.over_guess, Toast.LENGTH_SHORT); toast.setGravity(Gravity.CENTER, 0, 0); toast.show(); return; } else if(input < comp) { Toast toast = Toast.makeText(MainActivity.this, getString(R.string.guess_low, input), Toast.LENGTH_SHORT); toast.setGravity(Gravity.CENTER, 0, 0); toast.show(); } else if(input > comp) { Toast toast = Toast.makeText(MainActivity.this, getString(R.string.guess_high, input), Toast.LENGTH_SHORT); toast.setGravity(Gravity.CENTER, 0, 0); toast.show(); } else { Toast toast = Toast.makeText(MainActivity.this, getString(R.string.correct, comp, guesses), Toast.LENGTH_LONG); toast.setGravity(Gravity.CENTER, 0, 0); toast.show(); }
