Question

我已经进入我的AndroidManifest.xml并将标签更改为我的字符串资源，但是当我在手机上启动应用程序时，它只会显示＆＃34;数字＆＃34;标签。我确实成功地将它从Miwac更改为数字标签，但现在每个活动都会显示数字标签。

这是我的mainActivity.java

 package com.example.android.miwok;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;

import static com.example.android.miwok.R.id.phrases;

public class MainActivity extends AppCompatActivity {

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

        // Set the content of the activity to use the activity_main.xml layout file
        setContentView(R.layout.activity_main);
        // Find the View that shows the numbers category
        TextView numbers = (TextView) findViewById(R.id.numbers);

// Set a click listener on that View
        numbers.setOnClickListener(new View.OnClickListener() {
            // The code in this method will be executed when the numbers View is clicked on.
            @Override
            public void onClick(View view) {
                Intent numbersIntent = new Intent(MainActivity.this, NumbersActivity.class);
                startActivity(numbersIntent);
            }
        });
        TextView family = (TextView) findViewById(R.id.family);

// Set a click listener on that View
        family.setOnClickListener(new View.OnClickListener() {
            // The code in this method will be executed when the numbers View is clicked on.
            @Override
            public void onClick(View view) {
                Intent familyIntent = new Intent(MainActivity.this, NumbersActivity.class);
                startActivity(familyIntent);
            }
        });TextView colors = (TextView) findViewById(R.id.colors);

// Set a click listener on that View
        colors.setOnClickListener(new View.OnClickListener() {
            // The code in this method will be executed when the numbers View is clicked on.
            @Override
            public void onClick(View view) {
                Intent colorsIntent = new Intent(MainActivity.this, NumbersActivity.class);
                startActivity(colorsIntent);
            }
        });TextView phrases = (TextView) findViewById(R.id.phrases);

// Set a click listener on that View
        phrases.setOnClickListener(new View.OnClickListener() {
            // The code in this method will be executed when the numbers View is clicked on.
            @Override
            public void onClick(View view) {
                Intent phrasesIntent = new Intent(MainActivity.this, NumbersActivity.class);
                startActivity(phrasesIntent);
            }
        });
    }
    }

对于每个新意图，您将启动相同的“NumbersActivity”。将其替换为其他活动

 Intent numbersIntent = new Intent(MainActivity.this, NumbersActivity.class);
 startActivity(numbersIntent);

 Intent colorsIntent = new Intent(MainActivity.this, Colors.class);
 startActivity(colorsIntent);

 Intent phrasesIntent = new Intent(MainActivity.this, Phrases.class);
 startActivity(phrasesIntent);

为什么我的标签不会改变onClick
