Question

我尝试创建一个练习应用，将点击按钮上的state = { text: '', words: 0, reset: false, }; updateInput(event) { if (this.state.reset) { this.setState({ reset: false, }); return; } this.setState({ text: event.nativeEvent.text, }); } <TextInput value={this.state.text} onChange={this.updateInput.bind(this)} onKeyPress={({ nativeEvent }) => { if (nativeEvent.key === ' ') { this.setState({ text: '', words: this.state.words + 1, reset: true, }); console.log(this.state.text); console.log('onKeyPress worked!'); console.log( 'there are a total of ' + this.state.words + ' words!' ); } }} blurOnSubmit={false} autoFocus={true} autoCorrect={false} autoCompleteType={false} allowFontScaling={true} keyboardType="default" keyboardAppearance="dark" onSubmitEditing={event => { event.preventDefault(); this.setState({ text: '', words: this.state.words + 1, }); }} />更改为另一张图片。该应用程序崩溃了。我希望应用程序在单击按钮时将屏幕上的图像更改为另一图像。

以下是XML文件：-

public class MainActivity extends AppCompatActivity {
Button btn;
TextView txt;
ImageView imgView1 ;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    btn = findViewById(R.id.button);
    txt = findViewById(R.id.textView);
    imgView1 = (ImageView) findViewById(R.id.imageView1);


    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            txt.setText(getString(R.string.ChangedValue));
            imgView1.setImageResource(R.drawable.add);
        }
    });




}
}

错误：-Resources $ NotFoundException：资源ID＃0x7f060055

ResourcesNotFoundException意味着当找不到请求的资源时，资源API抛出Developer site。

简单来说，您尝试使用的可绘制对象，尺寸，布局，字符串或任何其他资源将不会出现在您的项目中。

解决方案：-请仔细阅读所有资源并检查其名称的拼写。任何小错误都会给我们这样的异常。
