java - 每当我点击按钮时 Android 应用程序就会关闭

Question

我正在为我的项目构建一个应用程序，其中包含一个布局，该布局可打开相机并拍照，而其他布局则将文本转换为语音，每当我单击导航到文本到语音布局的按钮时，该应用程序就会关闭我无法达到该布局

文本到语音代码在新项目中单独测试时工作正常，但当通过按钮链接为导航页面时它会关闭

//java代码//

     public class Text extends AppCompatActivity {


     Button ak,bk;
     protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.text);
    ak=(Button)findViewById(R.id.cam);
    ak.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i=new Intent(Text.this,Camera.class);
            startActivity(i);
        }
    });
    bk=(Button)findViewById(R.id.spe);
    bk.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent k=new Intent(Text.this,Speech.class);
            startActivity(k);
        }
    });
}

应用程序不断关闭而不是转到另一个页面

Answer 1

也许你可以改变

Intent k=new Intent(Text.this,Speech.class);

至

Intent k=new Intent(getApplicationContext(),Speech.class);
